Arsenal boss Arsene Wenger believes Louis van Gaal will turn Manchester United into title challengers again.
Wenger, who for 17 seasons went head to head with former United boss Sir Alex Ferguson, reckons the Dutchman's arrival will make next term a five-horse title race.
"He is going to be a fantastic manager in the Premier League," Wenger told beIN Sports.
"I liked how the decisions he made were clear, how the timing of his decisions were always right and in my opinion it was the right decision every time.
"I am sure that Manchester United will be competitors this year for the championship and that will be more interesting.
"Because he can beat maybe Arsenal but then he might lose to Chelsea, then you've got Manchester City as well as Liverpool. So yes, it's going to be an interesting league."
