Steve McClaren: 'Aleksandar Mitrovic must control emotions'

Newcastle United manager Steve McClaren has warned summer signing Aleksandar Mitrovic that he must learn to keep his emotions in check.

The Serbia international was shown a yellow card for a tackle on Swansea City's Neil Taylor soon after coming on during Saturday's meeting at the Liberty Stadium.

It comes just a week after an identical case on the opening weekend of the campaign, when Mitrovic lunged in on Southampton's Matt Targett.

"There was nothing in it, but there was a reaction from players and the crowd," McClaren told BBC Sport. "He's a physical player and we can't take that away from him.

"One thing we learned from Saturday, you've got to learn about emotional control. Referees need to be more aware - not be lenient, but allow the game to go on."

Mitrovic joined Newcastle from Anderlecht for a fee of £13m earlier this summer.
