Manchester United No2 Mike Phelan admits they face a big challenge against Stoke City.
The Reds' assistant manager says clashes with the Potters require precise planning.
"Stoke, for us, is as big a game as playing Chelsea, Arsenal or Liverpool, purely because they demand a high level of attention to detail," Phelan told United Review. "They are a very good team. They've sustained their Premier League status for a third successive season now and are a competitive side.
"They certainly give you a run for your money. We respect Stoke a lot for the way the club is run and for what they have achieved. One thing we do know is that we have to be fully focused when we play them."
