Arsenal went into the current international break off the back of an impressive win at West Ham. The next challenge is at Norwich on Saturday - and Mannone expects an equally tough assignment.
"It was very important [to win at West Ham] because we bounced back from the home loss to Chelsea," he told arsenal.com. "We did really well in two difficult games, one in the Champions League against Olympiacos and then West Ham away. That [West Ham] is a really difficult game because it is very physical and I thought we came out with a really good win.
"It is great for our confidence [to come from behind and win], the spirit in this team is great. It was great before but after the Chelsea defeat we felt a bit like we needed to come back and come back strongly. We managed to do it with two good games and we are looking forward for more wins.
"Norwich is another team that plays really well, especially at home. It is not an easy one, again, I would compare it to West Ham. It will be a difficult test for us, we need to dictate the game and impose ourselves. If we let them do what they know, it will be a difficult game.
"We need to stand up, defend well as we have been doing - that is always our base I think. From there we have massive quality up front and we can win the game."
