"It was a great win, there's only one way to win the cup, we knew we had to win the game and we did it in very good fashion," said Cech to chelseafc.com.
"It was important, any FA Cup progress is important for your season. We wanted to book a place at Wembley, we had great opposition and it was a great match. We are happy we managed to win the game.
"We seem to have a special relationship with the FA Cup; we treat it with respect, every season we try to win it and we get something back. We have another tough game against City, but it's a semi-final so you expect a tough game."
