Real's Ronaldo returns to training after injury

May 1 (Reuters) – Real Madrid forward Cristiano Ronaldo hasreturned to training after recovering from a hamstring injury and could be fit to face Manchester City in the Champions League semi-finals on Wednesday. Ronaldo has not featured since April 20, but could return for the second leg having missed last week's 0-0 draw at theEtihad Stadium. "Every Champions League match feels like the first," Ronaldo told the club's website. "And Real Madrid's priority is to win. "We know it will be a tough challenge, but everything is possible." The 31-year-old Portuguese trained with his team mates during the first half of Sunday's session before workingout on the pitch alone. "Manchester City are in the semi-finals because they are an excellent team," Ronaldo added. "Eliminating Paris St Germain is not easy, but they managed it. They're a team who have very few flaws." Striker Karim Benzema also continued his recovery from a hamstring injury and Alvaro Arbeloa - who has not played since early April - completed some running exercises. Ronaldo leads the Champions League scoring chartswith 16 goals this season, including a hat-trick in the quarter-final second-leg victory over Wolfsburg. "We had to win by three goals and I scored all three," Ronaldo said. "It was a special night. It needed to be the perfect evening and it was." (Reporting by Ed Dove, editing by Ed Osmond)
