MADRID — Cristiano Ronaldo says he wants to stay with Real Madrid until the end of his contract with the club. The 27-year-old Portuguese striker's contract with Real runs out in June 2015, but Spanish media have reported that he is unhappy at the club and may leave at the end of the season. The player has been linked to a move to Paris Saint-Germain or back to Manchester United. “I want to see out my contract at Real Madrid: I'm very clear about that. After that, well, I don't know what will happen in the future,” he said in an interview published on Fifa.com. Ronaldo said he still believes it is possible for the club to win La Liga despite falling 18 points behind leader and arch-rival Barcelona. “We haven't started the championship very well for sure. We know that La Liga's an uphill struggle for us now, but nothing is impossible in football,” he said. Real Madrid is in third place in the Spanish league, four points behind second-placed Atletico Madrid and has dropped even further behind Barcelona after it was held to a 0-0 draw at relegation-threatened Osasuna Saturday. Ronaldo also defended Real's Portuguese coach Jose Mourinho. “People do protest and you have to respect that, though I think they should be a bit patient with him,” Ronaldo said. “To me it's very clear that Mourinho always wants what's best for the club and will fight to the death to defend it. All of us who work alongside him know that, but you've still got to show respect for the fans' opinion.” — Agencies
