Cristiano Ronaldo has adapted his game dramatically, could play until he is 40, says Wayne Rooney

Wayne Rooney, Manchester United's all-time top scorer, added that his former team mate Cristiano Ronaldo is a "completely different player" to the one that left the club 12 years ago but can still keep up with the physical demands of the Premier League.

Manchester United forward Cristiano Ronaldo is capable of playing until he is 40 as he has adapted his playing style to extend his career, former captain Wayne Rooney said. Ronaldo, 36, spent six seasons at Old Trafford between 2003-09, winning eight major trophies, and rejoined United from Juventus last month on a two-year contract.
