Wales are unbeaten in this season’s Under-20 Six Nations while England have lost just once but have a better points difference, meaning Friday’s clash in north Wales is winner-takes-all.
The match is a 7.35pm kick-off at Parc Eirias, Colwyn Bay, and is screened live on S4C.
Title-holders England have brought wing Anthony Watson, prop Kyle Sinckler and hooker Nathan Morris into the starting XV following last week’s win over Italy.
