Cristiano Ronaldo has been offered to Manchester City.Corriere dello Sport says Ronaldo's representative Jorge Mendes has offered City an alternative option to Juventus striker by declaring that the 36-year-old could turn out in the blue half of Manchester this season.The report says Juventus would be willing to sell Ronaldo for just £25m this summer given he has just one year left on his contract, with the Serie A giants also keen on cutting the Portuguese striker's hefty wages loose.A potential Ronaldo move to City would be a hugely controversial transfer given the 36-year-old spent six successful seasons at the Premier League club's arch-rivals, Manchester United, scoring 118 goals in 292 games between 2003 and 2009.Ronaldo has always held a strong bond with the United fans, so a move to the Etihad Stadium would be seen as a betrayal.
