Arsenal FC vs. Olympiakos Live Stream: Watch Champions League Football

Arsenal looks to position themselves to lead Group B when they host Olympiakos, and they will try to not repeat their effort last week in the Premier League, which saw them lose to Chelsea.

Arsenal manager Arsene Wenger will have to fill a squad that matches up well with Olympiakos, but will have to do so without the likes of Abou Diaby, who was substituted with a thigh injury over the weekend. He will be kept company on the sidelines by Tomas Rosicky, who is recovering from an Achilles injury, and Bacary Sagna, who is still nursing a foot injury.

Arsene Wenger's team put themselves in great position early on in the group stage after they beat Montpellier in their opening game of Group B, and they currently are sharing the lead in points with FC Schalke.

Should Arsenal be able to gain full points with their match today, they would have a 6-point lead over Olympiakos after only two matches, which would be the same margin to Montpellier should they lose to FC Schalke in Gelsenkirchen.

Wenger will have to make his team ready after they were thoroughly dominated at home against Chelsea over the weekend, but the longtime Arsenal boss is confident that he will get the full effort from his players.

For Olympiakos, manger Leonardo Jardim is rumored to start Roy Carroll in goal, as he makes a return to England after having spent time with both Manchester United and West Ham.

Jardim was impressed with his club's win at Atromitos in domestic action over the weekend, but understands that Arsenal is a top club and will have to play mistake-free if they are to have a chance.

The Greek club will also have to forget the bad memories from last year after they lost to Arsenal 2-1 in the group stages.

Kickoff for the match is at 2:45 EDT and can be watched online here.
