Wales ended their Uefa Under-21 Championship qualifying campaign with a comprehensive defeat to group winners Czech Republic.
The visitors reached the hour mark trailing to Filip Novak's early opener, but four goals followed in 19 minutes.
Tomas Wagner and Ondrej Vanek struck first, before substitute Stanislav Tecl added the final two goals, one coming from the penalty spot.
It left Wales with three wins and a draw from their eight games.
Czech Republic will now go forward into the play-offs to fight for a place in eight-team finals, which takes place in Israel next year.
