And he insists there's more to come from his former Nottingham Forest protégé.
“Since then, and even since I've come back into the Club this time, his hold-up play has improved drastically. It startled me because that was an area of his play we felt he could improve on [then] – and he still can – but I think his hold-up play and his understanding of his runs has improved drastically.
“I think at the moment he's still got to get into the groove that he had pre-injury – there's certainly more to come. He's got to improve his all-round game from that, but I think MIch as well wants to push his limits to see how good he can be."
