He's 18 and the fans getting on his back is affecting him, could see it a mile a way. the gaffer needs to take him out the firing line for a game or two. Then tell him to keep it simple, pass and move. Don't try to carry the ball and loss it like he did a few times today.
The situation kind of reminds me of Edu in his last couple of seasons with us. Crowd on his back because of some bad performances and that fucked up his confidence. Vicious circle.
