Arsenal academy chief Liam Brady has paid tribute to Fabrice Muamba.

Brady worked with the Bolton Wanderers, who is in critical condition in hospital after collapsing on Saturday, as a junior at Arsenal.

"Like everyone else I am completely shocked. I was in Barcelona with our Under-14 team and I was watching the Tottenham v Bolton game on TV. I was completely horrified by what happened and we are hoping and willing him to pull through," Brady told arsenal.com.

"Fabrice was always a happy boy at Arsenal, a well-mannered boy. He seemed to really appreciate the opportunity he had and was fully intent on giving his best. He has been like that ever since he was 12.

"He comes to visit us, he calls in when he can. Fabrice remembers where he came from and he's a smashing young man. He's determined to make the best of his career and let's hope that determination helps him pull through the situation he is in."
