The Gunners are now gearing up for the second leg of the Europa League round of 16 tie against AC Milan on Thursday.
Arsenal registered their first league win in quite a while on Sunday as goals from Shkodran Mustafi, Pierre-Emerick Aubameyang and Henrikh Mkhitaryan secured a 3-0 win over Watford at the Emirates stadium.
That convincing result came on the back of a memorable trip to Italy last Thursday as the Gunners defeated AC Milan 2-0 at the San Siro.
Arsene Wenger will be hoping his side finishes off the job when they meet again with Milan in the second leg of the Europa League round of 16 tie tomorrow.
And present in training on Wednesday was Sead Kolasinac who has recovered from an injury he suffered in the first leg last week.
The 24-year-old will be hoping for another start with Nacho Monreal appearing to be still on the sidelines at the moment.
