There are eight games taking place this evening in the Champions League, with Arsenal, Barcelona, Chelsea and AC Milan all in action.

European champions Barcelona travel to Viktoria Plzen tonight having been given a boost by the news that winger Alexis Sanchez could return for the game at the Struncovy Sady Stadion.

Barca go into the game joint-top of Champions League Group H alongside Milan on seven points.

AC Milan are also away from home this evening as they travel to BATE Borisov, who along with Plzen have taken just one point from their three group games to date.

In Group F, table toppers Arsenal play host to Marseille knowing that avoiding defeat will see them close in on the knockout stages of the competition.

The Gunners will be boosted by their 5-3 win over Chelsea in the Premier League at the weekend, but for the Blues, they will need to bounce back from that defeat tonight when they travel to Genk.
