Arsenal and Barcelona are two of the sides looking to make it three wins out of three when the Champions League resumes this week. Here is a quick look at Tuesday’s matches:

Steaua v Basel

Steaua Bucharest, the 1986 champions, are looking for their first points in the Champions League this season after defeats to Schalke and Chelsea. Basel, semi-finalists in the Europa League last season, could not build on their surprise 2-1 victory at Chelsea, losing 1-0 at home to group leaders Schalke last time out.

Schalke v Chelsea

Chelsea and Schalke last met in the 2007/08 group stage. Schalke are hoping to welcome back goalkeeper Timo Hildebrand from a back injury, while Chelsea badly need a win in Gelsenkirchen to build on their 4-0 win at Steaua Bucharest.

Arsenal v Dortmund

Arsenal have managed to move to the top of the Premier League without a number of key players. Mathieu Flamini may miss Tuesday’s game after suffering concussion. The German side are without Nuri Sahin who has an ankle injury.

Marseille v Napoli

Brazilian defender Lucas Mendes will miss the game after suffering an ankle injury in Friday’s 1-0 defeat at Nice. With two defeats from their first two Group F matches, Marseille must beat the Italians to keep their knock-out stage hopes alive. Napoli could be without Argentine striker Gonzalo Higuain.

Porto v Zenit

Zenit’s record signing Hulk will make an emotional return to the club where he scored 78 goals. Zenit are on a hot streak with seven league successive wins but have just a single point from their European campaign. Porto have three points and will be looking to preserve their unbeaten home record against Russian sides.

Austria Vienna v Atletico

Diego Simeone’s men have two wins from two in the Champions League, including an impressive come from behind victory at Porto. Atletico are likely to be without Brazilian youngster Leo Baptistao and will most likely be replaced by 25-year-old Diego Costa.Celtic v Ajax

The Scottish champions desperately need a result in the first of two clashes with Ajax, but will be without captain Scott Brown and Kris Commons.

Ajax will be looking to at the very least put themselves in position for the Europa League spot.

AC Milan v Barcelona

Milan could count themselves fortunate to have grabbed a point against Ajax. However, they are also likely to have to call on third choice goalkeeper Marco Amelia as Christian Abbiati is injured and Gabrielnot on the list of the Champions League squad. For Barcelona, Carles Puyol started against Osasuna and Lionel Messi came on as a substitute, meaning they will be back in action after missing several games.AFP
