I don't think it's too much of as stretch to see that Benzema is going to be an immense player.
I don't think there will be a lot of change at United this summer, provided Tevez stays. If he leaves, then another foward / winger will come in (possibly Valencia).
The only change I see would be Valencia in for Nani if Tevez sticks round.
The rumours around Ronaldo and Vidic eill only occur if SAF wants them to leave, and I highly doubt that. Big players don't leave unless he wants them to, with the possible exception of Pique last year.
Ronaldo has that pre-contract cause of 25ish million doesnt he?, Madrid will have to pay him if he doesnt leave old traff
