Lately, I've seen more of Cristiano Ronaldo's six-pack than my own wife's breasts' - Oliver Kahn

German goalkeeping legend, Oliver Kahn, has taken a swipe Cristiano Ronaldo after a photo of the Real Madrid star wearing only his underwear while celebrating with his teammates, went viral.

Speaking to German broadcaster ZDF, Kahn said, "Lately, I've been seeing more of Cristiano Ronaldo's six-pack than my own wife's breasts. It seemed almost as if they were offended they had to play here in Wolfsburg," Kahn added.

The 46-year-old, who has moved into a career in punditry in Germany, claimed that both Ronaldo and Gareth Bale are too undisciplined in their defensive output to go the whole way in the Champions League.

He said: “Neither Cristiano nor Bale look comfortable with the defensive work and that always leaves space for the rival full-backs.”
