Manchester United boss Sir Alex Ferguson remains unhappy with the performance of ref Mark Clattenburg after Saturday's defeat at Bolton.

Ferguson has been charged by the FA for his bust-up with the match official and yesterday said: "You can expect a team in Bolton's position to play that way.

"You expect a team near the bottom to battle, scrap and fight.

"Obviously they do not have the quality of opponents like ourselves. That is why they we are in different positions in the league.

"But the key thing is how the referee controls it. He is the arbiter in terms of the application of the rules of football. That is where we feel a bit aggrieved."
