Manchester United manager Louis van Gaal believes that Arsene Wenger deserves special praise for the commitment that he has shown to Arsenal.

The Frenchman has been in charge of the Gunners for nearly two decades, although he has come under increasing pressure in recent years following a barren run which has seen the club collect just one piece of silverware since 2005.

Ahead of Monday night's FA Cup quarter-final clash between the two sides, Van Gaal has described his opposite number's achievements in North London as "amazing".

"In my opinion what he has done is amazing," BT Sport quotes the Dutchman as saying. "It can only be in England, I believe, where managers are so long committed with one club.

"It shows how much he can mean for a club as a manager. I like that - like Sir Alex Ferguson, Arsene Wenger - I think it's fantastic that you can do that."

Van Gaal also admitted that finishing inside the Premier League's top-four places takes priority over winning a trophy this season.
