Real Madrid attacker Cristiano Ronaldo has hinted that he could leave La Liga in the future, with a return to the Premier League a realistic option for the Portugal international.Reports that Manchester City had made a big money offer for Ronaldo earlier this summer were quickly dismissed, but the Citizens will be pleased to hear that the former Manchester United star is tempted by the prospect of returning to England at a later stage in his career."Whether there is a chance that I will return to the Premier League one day? Possibly, you never know what will happen," Ronaldo was quoted as saying in a press conference.The 26-year-old then went on to discuss the upcoming Supercopa tie with Barcelona and stated that the Santiago Bernabeu side are eager to beat their rivals."It's always important to win, so we also want to win the Supercopa. We are focusing on our training camp in China now, but we'll make sure we are ready when Barcelona await."The first leg of the Supercopa takes place at the Santiago Bernabeu on August 14, with the return being played at Camp Nou four days later.Source: Goal.com
