After Arsenal's 3-1 defeat at Barcelona on Tuesday, we asked fans to share their thoughts on the game via Twitter.

Many of you got in touch and below is a selection of the fans' thoughts.

If you don't already follow us on Twitter and want to have your say, you can find us here: @Arsenal

@andresinjunior - We have to keep our heads up and win the Premier League and FA Cup.

@rantonika - We need the referees to be humans, not robots.

@jimpow77 - I think we missed Theo Walcott, he made a massive difference in the first leg.

@jiimii33 - With 11 men in the second half it would have been a different stroy.

@futobolica - Arsenal have shown the world that they have grown up both physically and mentally. Unfortunately decisions cost us a win.

@hokinchan - There were some soft yellow cards against us. Nasri and Wilshere copped some hard challenges and the Barca players got away with it.

@DebbieB48 - We would have gone through with 11 men.

@ian__godfrey - Absolutely disgraceful refereeing! Other than that we played excellently, there's still a double up for grabs.
