Arsenal manager Arsene Wenger believes his side was unlucky to lose their Champions League clash with Dinamo Zagreb.

Wenger believes the major decisions in the 2-1 defeat in Croatia, including Olivier Giroud's first-half red card, went against his team.

When asked about the result, he said: "It's difficult because we had a lot of the ball and we had early chances. We were a bit unlucky tonight.

"I believe the first goal was offside and then afterwards the sending off was very harsh. We have to look at ourselves as well because the second goal killed our game.

"We are good enough to defend corners like that well. Apart from that we had a lot of the ball when it was 10 against 11.

"They were committed, they defended well and sometimes I felt that they stopped us from gaining an advantage without being punished by the referee, especially on counter-attacks where we had to play 10 against 11 in one half. We were not at our best but neither was the referee tonight."
