Cristiano Ronaldo is ready to slap in a transfer request at Manchester United, it has been revealed.

The Sun says confrontational remarks after the Champions League final loss are certain to put him on a collision course with Sir Alex Ferguson.

When asked if he would still be at the club next season, Ronaldo, 24, would only reply: “I’ve played many games under a lot of pressure. The future? We’ll see.”

Ron is aware he is a £50million target for Real Madrid, the club that desperately tried to lure him last summer.

But he added: “My future for now is the national team, we must win to be back on track in the World Cup qualifiers.

“I don’t want to talk about clubs, I want to rest, go on holidays because I’m very tired.”

But the Portuguese could not resist another dig at Ferguson and United’s tactics in their dismal 2-0 defeat to Barcelona in Rome.

He even claimed he did not know what position he would be playing in before the game.

Ronaldo said: “Ferguson did not tell me anything. Nothing.

“I didn’t realise I was to play as a striker. Against Arsenal in the semi second leg I played and played well but that is all.”
