Manchester United have already pencilled in Cristiano Ronaldo for his 'debut' second time around in preseason.

The Sun says they hope to sign the world superstar for £65million - and complete the biggest transfer in British football history.

United want to unveil Ronaldo on August 8 and then play him in Rio Ferdinand's testimonial against Sevilla the day after.

But Ronaldo himself last night delivered Old Trafford chiefs a blow, insisting he has still not ruled out a new deal with Real Madrid.

He said: "I'm calm. I'm not worried about it, I know we are going to reach an agreement to sign a new deal and for that if I am honest, I'm not preoccupied about it."
