He told manutd.com: "I’ve been impressed with West Brom and Hull. Both teams have good young managers in Tony Mowbray and Phil Brown. It’s very difficult for teams coming up from the Championship and trying to make it in the Premier League. But they got off to a good start and you have to respect that. We expect a tough game on Saturday.
"They won’t have had as many players away on the international break, so they will have been working all week to prepare for this game. We only start training as a group on Friday, so we know we have to be ready for them."
