Wales coach Ryan Giggs admits he has concerns about Ethan Ampadu's struggles at RB Leipzig.

Chelsea defender Ampadu's pre-season move to the Bundesliga was hailed as a smart move given that the teenager has had limited opportunities since joining Chelsea from Exeter in 2017.

But Ampadu has yet to make his Leipzig debut, despite being a regular member of their matchday squad, and the 19-year-old's only senior appearance this season came in Wales' European Championship qualifying win against Azerbaijan last month.

"It is a concern because Ethan is at the age now where he has to play," Giggs said ahead of Wales' Euro 2020 qualifier in Slovakia on Thursday.

"He's had a few problems there injury-wise, nothing serious but little aches and pains. The last few camps he's looked so much better in training.

"He is such a talent it's hard to ignore. But it's very difficult for him to play 90 minutes and back-to-back games, because he's not had the minutes."
