Arsenal captain Cesc Fabregas has rapped teammates for not having the bottle to win big games. Fabregas has accused Arsenal of failing to tackle crucial games head on and fears Manchester United are mentally stronger than the Gunners.
"Sometimes we seem scared of losing big games," he said. "We don't really go for it and we're tempted to drop back and see what the opposition will do.
"We look to see if we are capable of beating them by what they are doing and how good they are on the day, instead of us going forward causing them problems and dominating the game ourselves."
Arsenal skipper Fabregas made his comeback from a hamstring injury in last week's defeat at Old Trafford and revealed his fears after United physically dominated Arsenal.
"They were more aggressive than us," he said. "They have a belief that comes from not losing this season.
"I am realising more and more that football is about confidence and mentality. Sometimes you do the right thing, but if people tell you it is not right you start believing it."
