It's difficult to stop footballers from enjoying themselves having a kick about. It's even more difficult to do so if there are three World Cup winners having fun in one of the games most iconic stadia. 

On Saturday afternoon, Ronaldinho, Robert Pires and Cafu took part in Unicef's Match for Children at Old Trafford. The game was organised by Unicef ambassador David Beckham and starred some of the games most iconic players.

The excellent Copa90 recorded footage of the three stars warming up together and effortlessly juggling the ball between each other. It doesn't matter if they are retired or not, the nonchalant skill and effort is exceptional.
