Arsenal captain Cesc Fabregas insists they will overturn Manchester United's 1-0 lead in the second-leg of their Champions League semi.
The Spain midfielder said: "How much stronger are we at home? We showed that in the League, by beating them and scoring two goals.
"Let's think about the League, and the tie is still open. You look at the 1-0 scoreline, and we have seen worse things than that in the Champions League. Man United deserved to win, but now it is up to us to play well at The Emirates and beat them.
"We have to be more clinical in front of goal - that's for sure. We passed the ball a lot and combined very well, but we were not clinical enough. That is what we have to improve."
