Swansea City boss Paul Clement is critical of Manchester City's players going into tomorrow's clash.
Clement has sided with Manchester United in their row with City after Sunday's derby bust-up.
"Emotions run high in games, but when away from home you should celebrate in an appropriate manner with your supporters," Clement said.
"Then make your way back to the dressing room and enjoy it as a team there.
"You don't want any unnecessary confrontation and conflict. It does happen, but you want to try and avoid it."
On facing City, Clement added: "We know we're not going to have as much of the ball as them, but can we create a couple of opportunities and make them count?"
