id rather not see him in the Cahill role to be honest.
Cahill fights and tussles for the ball, billy doesnt. he seems to back out of 50/50 balls all the time too. i dont think hes got that hint of aggression that you need to play in the hole that Cahill and even Fellaini have. dont get me wrong i think he will come good, but until he settles into the squad im not sure we'll get to see what he can really do.
