Hallam Amos’s 21st birthday present from Wales coach Warren Gatland is a place in the starting line-up for the crunch Rugby World Cup Pool A clash with hosts England on Saturday at Twickenham.

Amos replaces the experienced Alex Cuthbert, who drops to the bench after a series of disappointing performances, in a starting XV patched together after injuries had cost Gatland several key players over the past few weeks.

There was no place for experienced halfback Mike Phillips, who was called up when first choice Rhys Webb was ruled out of the tournament before it began.

England and Wales – who both still have two-time champions Australia to play – won their opening matches against Fiji and Uruguay respectively.

Team (15-1):

Liam Williams; George North, Scott Williams, Jamie Roberts, Hallam Amos; Dan Biggar, Gareth Davies; Taulupe Faletau, Sam Warburton (capt), Dan Lydiate; Alun Wyn Jones, Bradley Davies; Tomas Francis, Scott Baldwin, Gethin Jenkins. Res: Ken Owens, Aaron Jarvis, Samson Lee, Luke Charteris, Justin Tipuric, Lloyd Williams, Rhys Priestland, Alex Cuthbert.
