Wales will take two right backs to the Euros. Connor Roberts of Swansea is a certainty and will start the tournament as first choice as he's been excellent for Wales over the last two years. The second RB as it stands will be Chris Gunter, a great servant for Wales with 96 caps but who is by now Reading's second choice RB (and has hardly started for Wales in recent years).
As a Welshman, taking Neco to the Euros is a no brainer! Considering that Ampadu has been one of the first name on the Welsh teamsheet for the past two years (when he's played a grand total of 3 league games for Chelsea/Leipzig), I think Giggs will take him.
