Arsenal v Olympiacos (20:00 BST)

This will be a trip down memory lane for Mikel Arteta as he comes up against one of his childhood coaches in Jose Luis Mendilibar.
At 13, Arteta was in the Athletic Club youth system where Mendilibar was his coach.
"They have a really, really good manager, which I know since I was 13 because he was my coach at that period, and I know how he works, I know how efficient he is in what he does," Arteta said.
"That's why I'm saying that it is going to be a really tough match."
