His hat-trick at Bolton on Saturday was his second in successive games, taking his overall tally to eight goals in four matches.
"This is probably Wayne's best season so far and I am expecting big things from him," said Carrick.
"He has done well in the past but he is getting more mature. He is handling things well and going from strength to strength.
"Sometimes he plays well but because he hasn't scored, people don't think he has played well. They just judge him on his goals.
"To score and perform the way he has is brilliant."
