Lamine Yamal delivered a man-of-the-match performance as Barcelona overwhelmed Turkish giants Galatasaray on their home turf. The victory puts Barcelona at the top of the table for now, with head coach Hansi Flick hoping his side can maintain the momentum.

Elsewhere, Atlético Madrid overcame a 10-man Manchester United at home, while Bayern München were held to an entertaining 3-3 draw by Norwegian side Viking in a dramatic encounter.

Arsenal also secured a convincing victory over Lille in an eventful round of UEFA Champions League fixtures. Here is a recap of the key results.

Arsenal 3-0 Lille

Under-fire star Bukayo Saka came off the bench to silence his critics with an impressive performance as Arsenal cruised to victory over Lille.

In a closely contested encounter, Jurrien Timber broke the deadlock in the 64th minute to put the Gunners ahead. Three minutes later, Eberechi Eze doubled Arsenal’s advantage, with Saka providing the assist.

Saka, who has struggled to reach his usual standards this season, showed glimpses of his best form and soon got on the scoresheet himself, finding the net in the 71st minute to put the result beyond Lille’s reach.

It was a flawless start for Mikel Arteta’s men, who will be eager to maintain their momentum as they pursue Europe’s most coveted club trophy.

Atlético Madrid 2-0 Manchester United

Michael Carrick’s struggles continued as Diego Simeone’s men capitalised on home advantage to secure victory over Manchester United.

It has been a subdued start to the season for the Red Devils, who have yet to demonstrate the consistency expected of a side competing in the UEFA Champions League.

United’s task became more difficult when Pablo Barrios produced a spectacular finish in the first minute to give Atlético an early lead. The match subsequently developed into an end-to-end contest, but the visitors struggled to find a way past Madrid’s defence.

Atlético thought they had doubled their advantage shortly before half-time, only for the goal to be ruled out.

With United pushing for an equaliser, defensive frailties eventually proved costly. Leny Yoro was shown a red card in the 71st minute for a professional foul, leaving the visitors with 10 men.

Atlético took advantage of their numerical superiority, with Ademola Lookman extending the hosts’ lead to 2-0 as Simeone’s side collected their first three points of the Champions League season.

Galatasaray 1-4 Barcelona

Barcelona produced an emphatic comeback to defeat Galatasaray 4-1 after falling behind in the first half.

The hosts took the lead through Aleksey Batrakov in the 28th minute, but Barcelona responded with sustained attacking pressure. João Cancelo restored parity in the 43rd minute, ensuring the visitors went into the break on level terms.

Fermín López put Hansi Flick’s men ahead for the first time in the 50th minute before Lamine Yamal, who proved a constant threat to the opposition defence, set up Anthony Gordon to make it 3-1 in the 53rd minute.

Barcelona continued to press, and substitute Karim Adeyemi scored their fourth goal following an assist from fellow substitute Gabriel Jesus, putting the result beyond doubt.

The emphatic victory propelled Barcelona to the top of the table on goal difference.

Viking 3-3 Bayern München

Champions League debutants Viking proved a formidable challenge for Bayern München, denying the German giants maximum points in a fixture that appeared straightforward on paper.

The hosts made a blistering start, with Gianni Stensness opening the scoring in the second minute before Peter Christiansen doubled Viking’s advantage in the 38th minute.

Viking went into half-time leading 2-0, but Vincent Kompany’s men mounted a determined comeback after the restart.

Harry Kane struck in the 54th and 60th minutes to bring Bayern level, shifting the momentum in favour of the visitors.

Luis Díaz then appeared to have completed the turnaround when he scored in the 71st minute to give Bayern their first lead of the match.

However, the contest took another dramatic turn when Michael Olise received his second booking just two minutes later, reducing Bayern to 10 men.

Viking capitalised on their numerical advantage, with Herman Haugen scoring a late equaliser to secure a memorable 3-3 draw and deny Bayern victory.
