Cesc Fabregas says that Arsenal's victory over Manchester United at the Emirates this season gives them faith that the Champions League tie is not over.
The Spaniard was part of the the Gunners' side beaten 1-0 by United at Old Trafford, but says it will be a different story at the Emirates.
He points towards Arsenal's 2-1 win (though of course that scoreline would not be enough) over United back in November when Samir Nasri scored twice.
"How much stronger are we at home? We showed that in the league, by beating them and scoring two goals," said Fabregas.
"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."
