Manchester United boss Ole Gunnar Solskjaer has rejected Rio Ferdinand's criticism of Cristiano Ronaldo during defeat at Young Boys in Berne.

Ferdinand suggested the United boss should have told Ronaldo to sit down after the subbed Portuguese superstar jumped from the bench to venture into his technical area during the shock 2-1 Champions League defeat to Young Boys on Tuesday night.

Solskjaer hit back: “Rio again, you know, sometimes he comments on things he doesn't really know.

“It should have been a yellow card for the boy when he brought down Nemanja.

“Both Bruno and Cristiano, as competitive as they are, suddenly I had them on my shoulder.

“They were there for a brief spell and shouted to the referee.

“That was the aggravation of getting a few bad decisions against us. But then Cristiano sat down, Bruno sat down. We know that there is only one man allowed in that technical area and that's either me or Carras (Michael Carrick) or Mick (Phelan) or Kieran (McKenna) who is up there."

Solskjaer added: “That was just a spur-of-the-moment, should-have-been-sent-off, that No.35, Martins.

“So I don't have any problem with them showing some passion and then going back down.

“It's not like he (Ronaldo) was coaching the players. No."
