Bolton boss Coyle: England awaits for Muamba
"I have absolutely loved working with Fab since I have been at the club," he told the Bolton News.
"He's already an England Under-21 international, and has a lot of experience at that level of football.
"His strength and size is there for all to see, as is his ability to tackle and chase in the middle of the park. There is always a call for that kind of player.
"The exciting thing from my point of view, though, is that there is a lot more to come from him."
