Cape Town - Petr Cech says Arsenal came through a difficult period to deservedly beat Manchester City and stake their place in the FA Cup final.
Alexis Sanchez scored an extra-time winner to secure a 2-1 win at Wembley on Sunday after Nacho Monreal had cancelled out Sergio Aguero's opener.
The Gunners' stopper also dismissed claims that the club's recent woes are down to a 'lack of leaders' at the club.
"I think it's easy to hide behind 'oh they lack leaders but they have leaders'. You need to see behind the scenes how well the team works and how we operate," Cech said.
"Sometimes you have periods of games where you prepare and do the right things but the game starts and it goes completely wrong.
"We had a difficult period where the team was losing games it should have not lost and obviously you come to the situation where you play under pressure and need to find a way out. Sometimes you find a way out quickly and sometimes it takes a bit of time."
Arsenal, who will now face Chelsea in the final at Wembley on May 27, are currently seventh in the Premier League standings, seven points behind fourth-placed Manchester City.
Up next for Arsenal is a clash with Leicester City on Wednesday ahead of the north London derby with Tottenham Hotspur on Sunday.
Kick off is at 20:45.
