Wolves boss Nuno expects big things from Jesus Vallejo this season.
The defender arrived this month on-loan from Real Madrid.
Nuno, ahead of their Europa League qualifier tonight against Pyunik, said: “We try to get maximum information (on potential signings) and at the same time try to be discreet, which is not easy.
“Regarding his characteristics as a footballer, we know him, we had a lot of observation, then we try to get information on his character, and we're delighted that he's joined us, he's a fantastic boy."
