The Europa League can wait another game. Arsenal did what they had to do in their Champions League match against Dinamo Zagreb at the Emirates and not it is a straight shootout between them and Olympiakos, after the Greek side were, expectedly, overwhelmed by Bayern Munich.

Arsenal needed to beat Dinamo Zagreb and hope that Olympiakos would not get a draw or better result at the Allianz Arena to keep their hopes alive of making it to the last 16 of the Champions League.

Olympiakos were thumped 4-0 by Bayern Munich and two first half goals and another one in the second 45 gave Arsenal a not-that-worrisome-at-all 3-0 victory over Dinamo Zagreb, with Mesut Ozil and Alexis Sanchez getting on the scoresheet.

Arsenal, as expected, went all out in attack from minute one, and after a fair few ooh and aah moments, they finally broke through the Zagreb defence. It was, ironically, a quick counter-attack that opened the game up. A ping-ping of passes and Sanchez had the ball on the right. The Chilean looked up and found a perfect cross for Ozil, who, after being left alone owing to a brilliant run from Olivier Giroud, headed home from five yards.

Four minutes after the opening goal, Arsenal were 2-0 up on 33 minutes, and this was all Dinamo Zagreb's own making. Leonardo Sigali gave the ball away to Monreal, who then raced into the box, before squaring the ball for Sanchez to tap home.

Two goals down, Dinamo Zagreb had to come out and try get something if they were to keep their own hopes of staying in the Champions League alive, but Arsenal never really looked too worried, with Petr Cech only needing to make one big save, that too after Sanchez had put the home team 3-0 ahead.

It was a wonderful goal too, worked Arsenal-style, with plenty of passes and then a cut-in from Joel Campbell and perfect through ball for Sanchez, who took the ball around the goalkeeper Eduardo before slamming it to the empty net from a remote angle.

Wenger also had the opportunity to give Aaron Ramsey some game time on the pitch after a month out with a hamstring twang, as the fans enjoyed themselves a fair bit after a couple of forgettable outings.

Now it is all about the match against Olympiakos, with Arsenal needing to better the result of when the two teams met in London, which the Greek side won 3-2.
