Premier League side Wolves are busy freeing up space on their wage bill this week.
The Molineux Stadium team are hoping to add more signings to manager Gary O'Neil's squad.
However, they must sell or loan out to buy, and they have been aided by winger Goncalo Guedes leaving.
Guedes has rejoined Benfica on a season-long loan deal to get regular first team football.
The club's sporting director Matt Hobbs said: "After the tough period Goncalo had with the injury last year, it's important for him to go out and get as many minutes as possible, in an environment he knows well, at a club which knows him well.
"They've been a big part of his rehab, so it's a move which makes sense. We had to make sure he was going to play enough and with all the competitions Benfica are in, he's going to play a lot of games.
"Also, the fact we can use his wages to hopefully supplement other deals this last week [of the window] can only be a positive for us. It frees up money to be spent elsewhere and gives him an opportunity to play games."
