Speaking to the CT, Chris Coleman said: "It's my mistake. I thought he was ready and he wasn't.
"He will be fine. I put him in and I take responsbility for that but he has done well in training and he will get over it because he is going to be a good player.
"It can happen to anyone. I watched Fulham play Juventus two weeks ago and I saw Fabio Cannavaro, one of the best defenders on the planet in the last ten-fifteen years have a nightmare.
"Defenders can have bad times just as midfielders have bad games or strikers miss open goals but the important thing is how you bounce back from something like that. It's no good saying you've got to forget about it because you have to do the exact opposite to that. Football is a learning curve and you should always remember when you have a tough time because that's how you become a better player."
