Owen Beck was unable to play for Wales Under-21s against Czech Republic because of an “administrative error”.

Beck had initially been named in Craig Bellamy’s senior squad, but it was announced on Thursday night that the full-back would instead link up with the youngsters.

The Liverpool loanee was one of several key players unable to feature at Rodney Parade, along with Rubin Colwill.

Matty Jones’ side went on to suffer a 2-1 defeat, missing out on automatic qualification for next year’s European Championships.

Ahead of the game, Jones told Sgorgio: “There has been an administrative issue, an error, that occurred.

“It has been really unfortunate and there will be a review from the FAW going forward to rectify the issue and have a clear explanation.

“It is really unfortunate that we are missing these key players. My initial reaction is we have been used to missing them and been able to adapt.

“We have certainly got the strength within the squad to facilitate that. It wasn’t ideal and it has certainly been a test of my management skill, with regards to dealing with staff and players.”

The Welsh youngsters needed at least a point to be in with a chance of finishing top of the group. They are back in action on Tuesday night when they take on Slovakia.
