Doyle joined Wolves in a club record £6.5million deal over the summer and McCarthy insists the striker is worth every penny.
“I knew what I was getting when I signed him,” said the manager.
“He has been everything I thought he would be – and he is a great lad.
“‘Doyler’ is a good footballer – and the fans have taken to him as well, because he plays well and scores goals.
“He is such a likeable character, and anyone who has spoken to him will know that.”
