Champions League Returns: Key Matches and Predictions

The Champions League is back on a Wednesday night, and it returns with noise: Liverpool against Atletico Madrid at Anfield, PSG beginning their title defence in Paris, Arsenal back on the road after last season’s heartbreak, and the new-look Camp Nou reopening its doors to Europe.

It is the first real temperature check of the 2026–27 campaign. Some giants look ready. Others are still rubbing sleep from their eyes.

FC Barcelona vs Feyenoord: The lights back on at the (new) Camp Nou

European football returns to the (new) Camp Nou with Barcelona already moving at a frightening pace.

Hansi Flick has not found his “tier 1” striker yet. He has found goals everywhere else. Four wins from four in La Liga, and in three of those they have hit five. Raphinha has exploded out of the blocks with six goals in four games, Lamine Yamal and Fermin Lopez have four each, and Barcelona are slicing through low blocks rather than moaning about them.

They will be without Frenkie de Jong, the only significant absentee, but the squad has been built to absorb that kind of loss. Rodri and Anthony Gordon now add Premier League steel and directness to a side already rich in technicians. At home, with that firepower and that crowd, Barcelona will expect to roll over almost anyone.

Feyenoord arrive unbeaten and unafraid, but fully aware of the size of the task. Luciano Valente and Gjivai Zechiel, both 22 and both pushing for Dutch national team recognition, have been central to their bright start. They bring energy, ambition and a touch of swagger.

They will need all three.

The gulf in individual quality, the setting, and Barcelona’s early-season rhythm all point one way.

Prediction: FC Barcelona 4–1 Feyenoord

Stuttgart vs Viking: A new face on the big stage

Stuttgart’s season so far has been a study in extremes. A 5–1 humiliation against Bayern Munich to open the Bundesliga, then a 4–1 dismantling of Köln on Friday. Same team, wildly different versions.

They finished fourth in Germany last season, powered by the emergence of 22-year-old Moroccan winger Bilal El Khannouss, whose direct running and creativity have made him a focal point of their attack. Luca Jaquez is among those missing, which trims the options, but not the ambition.

Across from them stand the newcomers. Viking, champions of Norway by a single point over Bodo/Glimt, are tasting the Champions League group stage for the first time after edging Dinamo Zagreb in the playoff. That alone tells you they are no soft touch.

They travel, though, without Veton Berisha and at least two other first-choice starters for their debut at this level. For a squad already punching above its traditional weight, those absences bite.

Norwegian football has been climbing steadily, and this will serve as an early test of where Viking truly sit in that rise. On squad value, depth and experience, Stuttgart have the edge. At home, with the Bundesliga pace already under their feet, they should show it.

Prediction: Stuttgart 3–1 Viking

PSG vs Slovan Bratislava: Champions in a fog

PSG are the defending kings of Europe, but they do not look like it.

The season began with a trophy – a 2–1 win over Aston Villa in the UEFA Super Cup – and then stalled. Defeat to Lens in the Trophee des Champions, draws against Rennes and Lille, and a loss to Monaco in Ligue 1 have left Luis Enrique with a squad that looks heavy-legged and oddly flat.

The talent is still absurd. Ferran Torres has arrived from Barcelona, Mika Godts from Ajax, Maghnes Akliouche to add more invention between the lines. The attacking trident remains their sharpest weapon: Desire Doue, Ousmane Dembele and Khvicha Kvaratskhelia, one of the few global superstars who did not go through the physical and emotional drain of the World Cup. On paper, that front line should terrify almost anyone.

On grass, though, PSG have been playing like a team with a hangover.

Slovan Bratislava come as Slovak champions, but as underdogs all the same. Under Yaya Toure they are only now stepping back into the European spotlight and have struggled for form domestically. The squad is a patchwork of profiles: veteran forwards Andraz Sporar and Tigran Barseghyan lead the line, while across the pitch they lack the sheer depth of international pedigree that PSG take for granted with players like Willian Pacho.

This is the kind of game PSG normally use to blow away the cobwebs. Wide spaces, long spells of possession, a chance for their stars to play with the handbrake off.

It feels like that kind of night again.

Prediction: PSG 4–0 Slovan Bratislava

Liverpool vs Atletico Madrid: Anfield meets Simeone’s steel

Two clubs who believe they can run with Europe’s elite, both parked just a step below the very top favourites. Liverpool against Atletico Madrid under the lights at Anfield, with Andoni Iraola taking charge of his first Champions League game for the club.

Liverpool’s domestic start has been steady rather than spectacular: two draws, then a win over Ipswich. The bigger concerns lie in availability. Federico Chiesa and Wataru Endo are out of European action, Hugo Ekitike and Conor Bradley are sidelined through injury. The defence will be anchored by Ronald Araujo, on loan from Barcelona, at centre-back.

On the right wing, Iraola faces his first big selection call. Does he unleash Bradley Barcola, the marquee signing, or lean on Victor Munoz, the reliable arrival from Osasuna? Barcola brings electricity and the promise of game-breaking moments. Munoz offers balance and work rate. Both will have to work ferociously against an Atletico side that rarely gives you space twice.

Atletico arrive with their own storm swirling. Julian Alvarez, a star for club and country, pushed for a move to Barcelona that the club refused. The window is shut, Alvarez is registered, but he is deeply unhappy under Diego Simeone and no longer the automatic starter he once was.

The squad around him has been reshaped. Cristian Romero has joined from Spurs to stiffen the back line, Alejandro Grimaldo from Leverkusen adds craft and set-piece quality, Jonathan David is in on loan from Juventus, while Kang-in Lee from PSG and Morten Hjulmand from Sporting CP give Simeone more technical options through midfield and attack. It is a refreshed, ambitious group that clearly expects to be a problem in the knockout rounds.

They are not flawless. Conceding three in defeat to Athletic Bilbao at the weekend exposed defensive gaps that Simeone will not tolerate for long.

At Anfield, with Liverpool still seeking rhythm and Atletico instinctively drawn to the idea of spoiling the party, this has the feel of a tight, tactical battle. Liverpool will push, roared on by the Kop. Atletico will bend, stall, and strike when they can.

In the end, the stalemate looks likely.

Prediction: Liverpool 1–1 Atletico Madrid

Sporting CP vs Galatasaray: Youth against experience

In Lisbon, two heavyweights from outside the traditional top five leagues square up, both harbouring ideas of a deep run. Sporting CP host Galatasaray in what could quietly become one of the most watchable fixtures of the round.

Galatasaray’s problem is clear and brutal: no Victor Osimhen. The Nigerian striker has already scored six goals in their 3-1-0 start to the season and is the spearhead of their attack. Take him out, and the entire shape of their threat changes.

Responsibility now shifts onto Gabriel Sara, the Brazilian attacking midfielder whose creativity will need to replace some of Osimhen’s raw finishing. The rest of the squad has the scars and savvy of years at the top level; with an average age of 29.3, Galatasaray are one of the most experienced sides in the competition.

Sporting are built very differently. They have opened their Liga Portugal campaign at 4-1-0, with Colombian international Luis Suarez and teenager Flavio Goncalves among the early standouts. The average starting age is 24.8, and it shows in their play: energetic, aggressive, unafraid to commit bodies forward.

At home, with that youthful intensity and the backing of Alvalade, Sporting should be the ones dictating tempo. Galatasaray still carry enough quality to hurt them, but without Osimhen the margin for error shrinks dramatically.

This feels like a narrow, hard-earned home win.

Prediction: Sporting CP 2–1 Galatasaray

Napoli vs Arsenal: Contenders on the march

Arsenal step back into the Champions League with a different kind of weight on their shoulders. ESPN and a host of pundits have pushed them among the favourites after last season’s final defeat to PSG. They look ready to embrace that expectation.

The early signs support the hype. A comfortable Community Shield win over Manchester City, followed by three straight Premier League victories, including impressive results against Aston Villa and Chelsea. The machine has not stalled.

They will be without William Saliba and Jurrien Timber at the back, losses that would unsettle most sides. Arsenal, though, have strengthened the spine. Bruno Guimaraes is available, whether from the start or off the bench, adding control and bite in midfield. On the wing, Christos Tzolis, signed from Brugge, has stepped straight into the starting XI, offering direct running and end product.

Napoli, by contrast, arrive wounded. Consecutive defeats in Serie A to Como and Inter Milan have cut into their confidence. Home advantage at least gives them a platform, but they enter this tie as clear underdogs.

Kevin De Bruyne, now 35, may begin on the bench, his minutes managed more carefully at this stage of his career. Scott McTominay remains out after heart surgery, another blow to their midfield options.

Arsenal will smell vulnerability. Their form, their depth, and their growing belief all point towards a statement performance in Naples.

Prediction: Napoli 1–3 Arsenal

The Champions League rarely follows the script, but if these opening nights are anything to go by, Europe’s hierarchy may be about to face a serious shake-up.
