Juan Mata takes side in Roy Keane's Man Utd disagreement with Nemanja Matic

Juan Mata has picked Nemanja Matic 's side in the Serbian midfielder's disagreement with Roy Keane over the level of desire at Manchester United.

Matic will leave Old Trafford at the end of the season after five years with the Red Devils, with only three games left of his United career. He played a starring role in the draw with Chelsea on Thursday, providing the assist for Cristiano Ronaldo 's goal.

After the game, Matic had made it clear how much he would miss the club when he does depart in the summer. And he insisted that he would remain a supporter of the Red Devils even following his exit.

"I will try to enjoy it of course, for me it was a pleasure and an honour to play at Old Trafford for five years, and like I said before the game, I will do my best until the end of the season to try and help the team," Matic told Sky Sports.

"Three more games to play, Manchester United will stay forever in my heart, along with Chelsea who I played with for many years, they both have a special place in my heart. I’m sure going forward, I will be a supporter and wish them all the best."

But those comments provoked a furious reaction from Keane who questioned the motivation of the squad. The Irishman also took aim at Ralf Rangnick's decision to bring on Mata, another player set to depart, on for the final 11 minutes of the game.

"Where's the standards at the club? Where's the desire to keep going, keep going until the end? The players, Matic talking about 'I'm leaving, I've had a great time... Man United will always be in my heart oh and Chelsea as well, by the way, oh and Benfica - don't forget them, they can't all be in your heart," Keane fumed

"Mata has come on for Man United again tonight, he's come on the last few games.
