Wolves – who travel to non-league Chorley in the FA Cup fourth round tomorrow – are working on completing a loan deal for the 29-year-old, with the option to then buy him from Spanish side Real Sociedad in the summer.
It is understood the club would have to pay around £17million to make his stay permanent.
The Brazilian has scored more than 50 La Liga goals for Sociedad, and Nuno said: “It’s always important to have experienced players.
“I always advocate for experience, and youth at the same time.
“This balance is the way we approach things.
“Having experienced players on the pitch is always helpful, as long as they do their tasks and perform well.”
When asked about the situation with Jose, Nuno did not want to go into great detail but said: “There are things going on.
“There’s nothing signed yet, so we can’t speak much about the situation.
“Until he becomes a Wolves player, (I won’t) speak too deeply about him, (we will) when things are all signed and ready to go.”
Nuno, meanwhile, says Wolves are going into the clash with sixth-tier Chorley as they would for any other game.
“It’s exactly the same, like last week, the previous week and games in front of us,” he added.
“It’s a game of football and we have to compete. We avoid any kind of interference from the outside, expectations. We just focus on the task ahead.
“The difference in divisions doesn’t assure you the game, so you have to compete and play.”
