Cristiano Ronaldo can continue playing until he is 40, according to his former Portugal team-mate Paulo Ferreira.
The Juventus striker is now 35 but remains one of the game's most lethal finishers, as he underlined earlier this month by equalling the Serie A record for scoring in 11 consecutive appearances.
Ferreira, who played in four major international tournaments with Ronaldo between 2004 and 2010, is not in the least surprised that his compatriot is still going strong at an age when most other forwards have either retired or are considering hanging up their boots.
