Arsenal boss Arsene Wenger says Kieran Gibbs is ready to face AC Milan.
Gibbs is the obvious candidate to start on the left and Wenger has no qualms about handing the 22-year-old his comeback in such a big game.
"To be a player is to come in and show how good you are when you get your chance," said the manager on Arsenal Player.
"I believe physically and mentally he is ready. But if I start him, which is not decided yet, I do not want to put too much pressure on him because we want a good team performance. Gibbs is a good player.
"I will find the most natural [solution], which means I will put Vermaelen back in the middle. Gibbs looks to be ready so I might look to start him but I have not decided completely yet."
