Arsenal boss Arsene Wenger is delighted to have Kieran Gibbs back and fully fit.
Wenger has challenged Gibbs to keep his more experienced team-mate Andre Santos at bay.
"They are competing for the left back spot and I must say that Gibbs is a big competitor because I rate Santos highly," he told Arsenal Player.
"To keep him out will demand some great performances and he is providing that at the moment. There is a big competition going on there."
