AC Milan coach Rino Gattuso has paid tribute to Manchester United manager Jose Mourinho.
The two teams will face-off in the US in the International Champions Cup.
“I think that Mourinho has been at the top for 20 years,” said Gattuso.
“He has won so much, he is always looking to get the best out of his players and it’s not a coincidence he has been winning for so long.
“He has a great mentality and he knows how to get into a player’s mindset.
“I think we are talking about one of the greatest Coaches in the world.
“I can assure you that being a Coach is more difficult than being a player.
“When you get to play these matches against these teams, for us it should be a source of pride and we can’t put in a bad performance.”
