3. Joe Marler & Billy Twelvetrees
Gloucester star Twelvetrees spent his youth at a succession of Sussex rugby clubs, including a spell at Haywards Heath in the same side as Harlequins prop Joe Marler.
The pair would eventually play for England together in 2013 with Twelvetrees since accumulating 22 caps and Marler 66. They’ve also both played for the British & Irish Lions.
