A professional and much-needed display by Arsenal saw them win at the San Siro last night, and they are now in pole position to reach the quarter-finals of the Europa League.
Both the Gunners and Milan need to win the competition if they are to qualify for the Champions League, and it was the Premier League side that controlled the game.
They took the lead on 15 minutes when Henrikh Mkhitaryan, who won the trophy last season with Manchester United, scored his first goal for the club.
On the stroke of half-time Aaron Ramsey added a second after rounding Gianluigi Donnarumma, giving Arsenal a deserved two-goal advantage.
Other than a Giacomo Bonaventura miss, the home side struggled to create anything of note and the result means that the Italian giants will have to score at least twice in London next week if they are to advance.
The result eases the pressure on Arsene Wenger following a diabolical run of form, but their season now hinges on claiming the Europa League for the first time.
