We are scared of losing in big games_Fabregas

Arsenal lost 1-0 to a Park Ji-sung header to continue a dire run against United, who beat them home and away in the league last season. Arsne Wenger's side have also lost their last four league games against Chelsea, the reigning champions.

"They [United] were more aggressive than us," F‡bregas said. "They have the belief that comes from not losing at all [in the league] this season. That gives you a lot of help mentally. I'm realising more and more that football is all about confidence and mentality. Sometimes you do the right thing but, if people tell you it's not right, you start believing it, even though you were right at first.
