#4 Rui Patricio
As clubs like Liverpool and Chelsea made big money signings such as Allison and Kepa to strengthen their goal-keeping departments, this signing of Wolves went considerably under the radar.
Rui Patricio arrived in a side that was excelling under their manager Nuno Espirito Santo and the Molineux knew that they've gotten a classy keeper, one who has international experience and has been in the game for a long time.
It's not been a magnificent season of course, but the Portuguese has made his presence to be felt. In 25 appearances, the keeper has made over 70 crucial saves but his contributions from the back have been really good too. He's made over 500 passes and has played 165 accurate long-balls.
He's not really commanding because he has only registered 6 punches and a similar number of high-claims but his positional awareness and his experience shows during the games. Wolves have got a very reliable keeper at the helm and they know it but it's about time that the league gives him a certain recognition as well.
