Wolves chief Kevin Thelwell has paid tribute to manager Nuno.
With managerless Arsenal eyeing the Portuguese, Thelwell has declared Nuno the club's best signing of the current ownership.
Thelwell told Marca: "I've said it many times. Nuno has been our best signing. He has improved us and has given us a very clear football identity and philosophy.
"You just have to see how we play, with or without the ball, to see how far we have come. His great work has taken us to another level."
On the 11 nationalities in the Wolves locker room, Thelwell added: "There are not so many, only some of the best [smiles]. We detect quality players in Portugal and Nuno knows them very well."
