Manchester United midfielder Ander Herrera says they're in great shape for the derby against Manchester City.

Herrera struck twice in victory over Aston Villa yesterday.

On next Sunday's home showdown with City, Herrera said: "A derby is always a derby.

"It's going to be a very good game for supporters, and we are lucky because we're going to play in front of our fans at Old Trafford. We feel confident when we play at Old Trafford in front of them, and now we have seven days to think about Manchester City, they play on Monday night and we can watch their game. Of course, we can't wait to play the derby in front of our fans and we're in a good moment."
