Manchester City have decided not to proceed in their bid to sign Brazilian star Ronaldo on a free transfer, despite their initial interest in his services. "We had shown a past interest in bringing the player to the football club in the right circumstances and spoke to him and his representatives," a City spokesman said. "However, we have chosen not to pursue the matter." The 31-year-old striker, who is currently out of contract, is in the middle of a lengthy rehab program, following a serious knee injury sustained last season with AC Milan. Earlier on Tuesday, Ronaldo revealed his excitement to join fellow countrymen Robinho, Jo and Elano at the City of Manchester Stadium, saying he received 'the best' from the Citizens. But English reports suggest that City backed down after undergoing medical tests on the player's knee ligaments.
