Manchester United boss Ole Gunnar Solskjaer is wary of his players turning on eachother.

Solskjaer claims United's desire to win against Crystal Palace 'boiled over into frustration' after Harry Maguire and Marcus Rashford were heard engaging in an X-rated exchange on the pitch.

As a result, Solskjaer has urged his players to control their emotions ahead of their clash with Premier League leaders Manchester City.

"Sometimes it has boiled over into frustration when it hasn't worked our way, we've got to stop that, the frustration on the pitch," he said.

"We want to win but don't let it affect your desire to do well.

"Don't let it affect your confidence or the team spirit."
