Wales U20s head coach Byron Hayward insists he is disappointed his former wing Josh Hathaway has jumped ship to play for England U20s.
Back-three speedster Hathaway, who is studying at Hartpury College, was capped by Wales U20s last season but is now in England's squad having left the Scarlets to join Gloucester.
And former Scarlets coach Hayward feels let down by Hathaway's actions having invested so much time and effort into his development.
