The prop grew up supporting Sarries, but following just a year with the black and reds, he moved to local rivals Harlequins, where he stayed until his professional retirement in May 2004, making a total of 290 appearances for the team. He also became an England and Lions legend.

The blockbusting No8, who grew up in Wales, explained in his new book how he supported Australia during the 2003 Rugby World Cup, even describing Sir Clive Woodward's England as "the enemy".

The boyhood Bath supporter joined their bitter rivals Leicester Tigers from Gloucester in 2013.
