Murray is currently on-loan at Watford.
He told BBC Radio 5Live: “He has transitioned into the Premier League really well from the Championship, coming from Brentford for a hefty amount of money.
“I think we have been quite reliant on him and I think Danny Welbeck has taken that struggle off his shoulders a little bit.
"I think we will be able to see much more of Neal getting on the ball.
“I'm not sure if he's an out-and-out No.9. He likes to drop down into the No.10 space.
“He likes to link the play but he has obviously shown in the past season that he can finish as well.
“He is an exciting player who I expect to keep improving."
