Mannone was in goal for Saturdayâ€™s 2-1 defeat against Manchester United and hopes the side will quickly learn from the mistakes made at Old Trafford.
â€śI think we need to really focus on ourselves now and be ready because Tuesday is another game like this one,â€ť he told Arsenal Player. â€śItâ€™s not good when you start like [we did at Old Trafford].
"We know that if you go 1-0 down, itâ€™s difficult because they defend really well. They put bodies behind the ball and itâ€™s difficult to break them down, especially if you donâ€™t increase the pace of the passing.
â€śWe passed it well but we donâ€™t do it enough to create chances. I think we only had two or three shots in the last five minutes. Obviously you canâ€™t win the game like that.
â€śWe just need to be focus and stick together because now is the time to react at a big club like Arsenal.â€ť
