Arsenal boss Arsene Wenger is delighted with Thomas Vermaelen's return from injury.
The Belgian defender struck in victory over West Brom on Saturday.
Wenger told Arsenal Player: "He is settling in very well and very quickly. We have a solid defence, solid centre-backs now. We can even rotate a little bit when needed. Overall compared to one month ago it just shows how quickly football can change.
"If people work hard, have a good attitude and good spirit, that's what we want to continue to do."
