“Craig has been unbelievable,” said the Dutch forward. “He came late in August and we did not pay a transfer fee.
“He has been a brilliant signing for us and looks even better now than he did the first time he came here.
“It’s not very often you can say that about a player who plays for a club in two spells.
“Usually the first time is better but this time, with Craig in better shape, he knows exactly what he can do and he’s really professional in training every day, not just helping himself but the whole of the squad.”
