Arsène Wenger praised his players for their approach to penalties after Arsenal reached the FA Cup final.
Lukasz Fabianski saved Wigan's first two penalties to emerge as the hero and Wenger was relieved and delighted afterwards.
We have gone through a very, very difficult week after last SundayArsène Wenger
"I was [believing we could win] but we are long enough in the game to know that penalties can go either way," he told Arsenal Player.
"It was important to start well and our keeper got us on the confidence level in a very good way. After that we took it in a very professional and calm way.
"We needed spirit and nerve. We have shown both I think because we were 1-0 down, we came back and we couldn't score the second goal. But overall we were spirit-wise and on the nervous front at the expected level.
"After that it's a typical cup game that we have seen in history. The only difference is when you experience it yourself it's difficult to go through. But we have done it well.
"Wigan won at Man City. You don't win at Man City by coincidence and they have shown why. We needed to be absolutely strong on the mental front and I'm happy that we have responded like that because we have been questioned on that front.
"We have gone through a very, very difficult week after last Sunday. We have shown the right response."Copyright 2015 The Arsenal Football Club plc. Permission to use quotations from this article is granted subject to appropriate credit being given to www.arsenal.com as the source 13 Apr 2014
