I don't agree. He got belters because he played him wrong, he basically bought another player he didn't know how to use correctly.
He looks better now because he's not having air balls lumped up to him.
If he comes good it won't be because Warnock saw the potential (he was never potentially going to be 8 foot tall winning headers from aimless balls pumped up the pitch) it will be because the manager is using him in a better way.
