half, although we could have been four-up in the first 20 minutes. De Gea’s save was one thing, but I also thought we were scrambling about to get through the game. But we’re fresher now and we’ve got a strong squad in terms of picking two teams."
Sir Alex believes Chelsea have had the rub of the green in terms of FA Cup draws in recent years but promises that the holders will have to do it the hard way in 2013.
"In the last few years, we’ve had some very difficult draws in the FA Cup," he added. "Chelsea have enjoyed a great benefit of home draws and I don’t think they have had one hard game in the run-up to the semi-finals over the years. That helps, no doubt about that. But they have us to play at Stamford Bridge and we won’t be easy for them."
