With just a week to go before the summer transfer windows open, speculations are rife on the transfer of some of the biggest names in today's football. The latest we hear is that Cristiano Ronaldo and Wayne Rooney could swap places in a £90million deal between Real Madrid and Manchester United.

Real Madrid are interested in Rooney, who is valued at around £30m, and its new boss Carlo Ancelotti has been a long-time admirer of England striker and would be happy to sacrifice Ronaldo if it meant he could sign the United star, reported Daily Star. 

Rooney, who has been sidelined ever since Robin van Persie joined Manchester United, reportedly placed transfer request to Sir Alex Ferguson before David Moyes took over. He has been linked to Arsenal for a £25million move despite Manchester United's reported policy not to sell their top players to Premier League rivals.

It is also reported that the 27-year-old England striker is interested in joining Chelsea. He still has two more years left with Old Trafford in his current deal.

Interestingly, reports were doing the rounds that Manchester United are keen to bring its former star Cristiano Ronaldo back to the club. They want to sign him after his contract with Real Madrid gets over in 2015, as they are currently not in the position to offer him as big as Monaco and Paris Saint Germain, according to The Independent.

Speculations were also rife that Real Madrid are going all out to sign new deal with the Portuguese star for a whopping fee.

Real Madrid are in advanced talks with Ronaldo's representatives over a deal totalling around €155 million over five years, with the Portuguese forward set to earn €15m annually after tax, which would make him the  world's highest-earning footballer, reported

The report came just a few days after the 28-year-old footballer announced on his facebook and twitter pages that the "news about my renewal with Real Madrid are false."
