Robbie joined stars including Michael Sheen, James Corden and Woody Harrelson earlier this week as the Soccer Aid players met up at a glitzy London hotel ahead of a gruelling few days at their training camp in Surrey.
Meeting for the first time, the two squads of players gathered for a bit of pre-match banter with team captains Robbie and Michael Sheen posing for a few snaps.
Robbie, who also performed at Soccer Aid 2006, commented: "I am so excited that Soccer Aid is back, and at Old Trafford once again. I have such amazing memories of my last game.”
“It will be a great time for football, with World Cup fever at boiling point, and there's never been a better time for us to show our support for UNICEF given the recent tragedies affecting children around the world. I hope the whole country will join me and support this fantastic event."
Welshman Sheen, star of The Damned United in which he played legendary football manager Brian Clough, has a few cunning tactics of his own to outsmart Robbie and the England boys, saying he aims to "put the ball in the opposition’s goal as many times as possible!" Easier said than done, Michael!
