From the MEN:
"Wayne is an exciting player and his improvement is so rapid that if it continues at this rate, his future is absolutely secure.
"He is looking great already but equally, I am sure we have not seen the best of him yet. He will be one of the greats and, as a club, we are very lucky to have him with us.
"We have seen with his temper that he is learning quickly how to keep a lid on it," added Charlton, who remains one of only two Englishman to have won the World Cup and European Cup.
"He knows when he has done wrong and he wants to put things right, which is great.
"No matter what he has achieved so far he wants to learn more, which is a great attribute to have. It means he won't get complacent and stand still."
