Champions League fixtures today - your guide to Tuesday's games

Galatasaray vs Bayern Munich - Group A

• Location: Istanbul, Turkey
• Stadium: Ali Sami Yen Spor Kompleksi
• Date: Tuesday 24 October
• Kick-off Time: 17:45 BST / 12:45 ET / 09:45 PT
• Referee: Davide Massa (ITA)
• VAR: Aleandro Di Paolo (ITA)

Bayern Munich have won 15 straight Champions League group games and are unbeaten in their last 36. So, yeah, they're pretty good at this stage of the competition.

After beating Manchester United and edging past Copenhagen, Bayern have a tough test in a hostile environment as they visit Galatasaray. Thomas Tuchel takes a thin, injury-hit squad to Istanbul to take on a side that are yet to taste defeat in 2023/24.

The Turkish giants entered Old Trafford and walked away with three points last time out as they attempt to beat Man Utd to second spot in the group.

Inter vs RB Salzburg - Group D

• Location: Milan, Italy
• Stadium: San Siro
• Date: Tuesday 24 October
• Kick-off Time: 17:45 BST / 12:45 ET / 09:45 PT
• Referee: François Letexier (FRA) 
• VAR: Jérôme Brisard (FRA) 

Last season's finalists produced a much more convincing display against Benfica on Matchday 2 after struggling in San Sebastian to open their account.

Inter were expected to coast in Group D and currently sit joint-top of the table with Real Sociedad.

The Nerazzurri returned to winning ways in Serie A at the weekend and next welcome RB Salzburg to San Siro. After the Austrians stunned Benfica on Matchday 1, they were cast aside by Real Sociedad last time out.

Manchester United vs Copenhagen - Group A

• Location: Manchester, England
• Stadium: Old Trafford
• Date: Tuesday 24 October
• Kick-off Time: 20:00 BST / 15:00 ET / 12:00 PT
• Referee: Marco Guida (ITA)
• VAR: Massimiliano Irrati (ITA)

Talk about must-win games.

United secured a victory without impressing at Sheffield United on Saturday night and now they must beat Copenhagen at Old Trafford on Tuesday night to ignite their Champions League campaign.

After losing their first two group games for the first time ever in this competition, Erik ten Hag's side face an uphill battle in their bid to advance into the round of 16. Danish giants Copenhagen have shown in their opening two games that they certainly won't be a walkover.

Sevilla vs Arsenal - Group B

• Location: Seville, Spain
• Stadium: Estadio Ramón Sánchez-Pizjuán
• Date: Tuesday 24 October
• Kick-off Time: 20:00 BST / 15:00 ET / 12:00 PT
• Referee: Glenn Nyberg (SWE)
• VAR: Marco Fritz (GER)

Another English side that could do with three points.

Arsenal were woeful at Chelsea on Saturday but walked away with a point to preserve their Premier League unbeaten status. A trip to Seville is up next for the Gunners after they were beaten by Lens in France earlier this month.

Mikel Arteta's squad is healthy, but they'll be up against an emboldened Sevilla outfit following the arrival of Diego Alonso as manager. Arsenal can ill afford to taste defeat in Spain.

Lens vs PSV - Group B

• Location: Lens, France
• Stadium: Stade Bollaert-Delelis
• Date: Tuesday 24 October
• Kick-off Time: 20:00 BST / 15:00 ET / 12:00 PT
• Referee: Radu Petrescu (ROU)
• VAR: Tomasz Kwiatkowski (POL)

Lens' Ligue 1 form continues to be indifferent but they were excellent against Arsenal on Matchday 2 as they secured a historic 2-1 win. After drawing in Seville to open their campaign, Lens have a serious chance of progressing.

However, a rampant PSV side are coming to town. While Peter Bosz's side have only picked up a point in Group B thus far, they've been nothing short of remarkable in the Eredivisie; winning all nine games and racking up a +27 goal difference.

They're a very good side but must get their Champions League campaign up and running with a win in Lens.

Union Berlin vs Napoli - Group C

• Location: Berlin, Germany
• Stadium: Olympiastadion
• Date: Tuesday 24 October
• Kick-off Time: 20:00 BST / 15:00 ET / 12:00 PT
• Referee: Irfan Peljto (BIH) 
• VAR: Pol van Boekel (NED) 

2023/24 is turning into a bit of a nightmare for Union Berlin, who have been cruelly beaten in both of their group encounters so far.

After Jude Bellingham broke their hearts at the death on Matchday 1, Braga rallied from 2-0 down to beat Union last time out. It was quite the occasion as the Olympiastadion played host and similar scenes are expected when Napoli come to town.

It's been a rather complex start to the season for the Scudetto holders, but they were victorious at the weekend and are in need of points in Group C after losing to Real Madrid last time out.

Braga vs Real Madrid - Group C

• Location: Braga, Portugal
• Stadium: Estádio Municipal de Braga
• Date: Tuesday 24 October
• Kick-off Time: 20:00 BST / 15:00 ET / 12:00 PT
• Referee: Michael Oliver (ENG)
• VAR: Stuart Attwell (ENG)

Real Madrid returned from the international break and earned a 1-1 draw with Sevilla at the weekend. It was a rusty display they must improve on as they travel to Braga.

While Braga currently sit fourth in the Primeira Liga, they're on a five-game win streak and will be confident of upsetting the odds on home soil when Madrid come to town.

Los Blancos have already taken full control of Group C after winning in Naples as they attempt to reclaim their European crown.

Benfica vs Real Sociedad - Group D

• Location: Lisbon, Portugal
• Stadium: Estádio da Luz
• Date: Tuesday 24 October
• Kick-off Time: 20:00 BST / 15:00 ET / 12:00 PT
• Referee: Clément Turpin (FRA)
• VAR: Willy Delajod (FRA) 

Benfica's opening game of the group turned into a disaster after Antonio Silva was sent off early on. They then succumbed to the unfavoured RB Salzburg and were second best in their defeat to Inter last time out.

Last season's dynamic quarter-finalists must win on home soil in this one, but an impressive Real Sociedad are visiting the Portuguese capital. The Spaniards have won four out of their last five in La Liga and currently look most likely to join Inter in the round of 16.
