Chris Coleman has insisted that Wales captain Ashley Williams was not to blame for an error which gifted Croatia their opening goal in a 2-0 defeat.
Coleman has refused to single out Williams for criticism and insisted that bad luck played a part in the Welsh defeat.
He told Sky Sports News: "Ashley Williams is a top class defender and the ball just got stuck. That end of the pitch is very sticky, and it just got stuck.
"That made it difficult for Lewis Price, the striker closes him down, the ball doesn't go anywhere and it ends up in the back of the net.
"It's amazing really, we can't keep a clean sheet. We made one mistake and got punished for it."
Defeat to Croatia leaves Wales second bottom of the group with just one win from four World Cup qualifying matches.
