Wolves captain Conor Coady is keen to see Raul Jimenez signed permanently.
The striker is currently on-loan from Benfica.
Coady told Sky Sports: "It is huge. It is for his presence in the changing room as well.
"We all see what he can do on the pitch at a weekend, but he brings a lot to the football club in general - it is like he has been at the football club for many years.
"It is important that we can keep him, but at the end of the day it is down to him and the clubs and they can come to some kind of decision, but we love having him here."
