An interesting line on the Ronaldo transfer in The Express where Richard Tanner suggests that the Real Madrid players don't want him there:

Senior Real stars – influential captain Raul, Spain’s Euro 2008-winning goalkeeper Iker Casillas and defender Michel Salgado – are all concerned at the negative impact Ronaldo’s arrival could have on team spirit.

The Mail suggests that other top clubs want us to keep the player as a point of principle:

It emerged last night that United have been contacted by several leading European clubs - including Spanish giants Barcelona - urging them to make a stand against the rise of player power by resisting Ronaldo's demands to be sold to Real Madrid.

The Telegraph speculate about when he might play again:

With his rehabilitation from surgery delaying his return to pre-season training, originally scheduled for July 14, United fear that he could be out of action until early September.
Such an absence would rule him out of the club's entire programme of pre-season friendlies, which begins at Aberdeen next Saturday, plus the opening fixtures of the Premier League season and the Uefa Super Cup clash against Zenit St Petersburg in Monaco on Aug 29.
With international fixtures pencilled in for the start of September, Ronaldo's first appearance of the season for United could come in the Premier League visit to Liverpool on Sept 13 - a week before the trip to Chelsea.
