Bayern Munich and Germany legend Oliver Kahn has aimed a hilarious barb at Real Madrid superstar Cristiano Ronaldo.

The Portuguese forward may be having a brilliant individual season - with 43 goals in 41 appearances this season - but Zinedine Zidane's team may well end the season without a trophy.

Los Blancos are out of the Copa Del Rey, are four points behind Barcelona in La Liga and trail unfancied Wolfsburg 2-0 after the first leg of their Champions League quarter-final.

Kahn, 46, is no stranger to success himself.

One of the best goalkeepers ever, Kahn won eight Bundesliga titles with Bayern Munich as well as six DFB-Pokal Cups, the Uefa Cup and the Champions League.

He also played 86 times for German, heping the team win Euro 96 and reach the final of the 2002 World Cup.

Kahn, however, has not been impressed with the seemingly endless shots of Ronaldo, mostly on his Instagram page, of the forward appearing topless.

"Lately, I've been seeing more of Cristiano Ronaldo's six-pack than my own wife's breasts," Kahn told German broadcaster ZDF.
