Manchester United No2 Mike Phelan has admitted his admiration for Leeds United boss Marcelo Bielsa.
The two great rivals will meet on Wednesday in Perth.
Phelan told manutd.com: "Bielsa is an excellent coach and a very deep thinker on the game. He is very passionate about football and how he wants his teams to play.
"I think we saw that last season when they went very, very close and probably should have got over the line. They just need that little bit extra but didn't quite have it. He works the team hard and took his principles that he wants them to adhere to. He'll be looking to take them all the way this time."
