With the signings of Jelle Van Damme and Steven Fletcher secured, plus the departure of Chris Iwelumo to Burnley, Mick McCarthy reckons there will still be more ins and outs at Molineux before the Premier League campaign begins in August.
"There is a bit of business still to be done," he confirmed. "And there will have to be a few move on as well.
"Andy Keogh started the season and then got injured and wasn't in the team. He does not want to be third or fourth choice, none of them do but that's how it can end up.
"Andrew Surman is a good player, he had a couple of games then didn't get his chance. He doesn't want to be third or fourth choice. If that's going to be the case they might want to move on.
"There are players who have helped us but it comes to a natural progression that they will move on - you can't just keep them here for back up. They have got to be seen to be fighting for a place.
"If they come back and are seen to be fighting for a place then I guess that (them leaving) won't happen. If it turns out that some players aren't fighting for a place then it does happen. It's natural progression.
"I know what will happen. They will all come back but I can only have a squad of 25. There's lads who haven't played as much as they would like but they all come back with renewed enthusiasm wanting to play - it's a good club and they all enjoy it here.
"But if it looks like they aren't going to play it will be: 'eh gaffer, do you see me fitting in here?'
"The players I mentioned (Keogh and Surman) might be the best ones in training and come back as fit as fleas.
"It's not an exact science (as to who leaves). I want them all to come back and fight for a spot - Richard Stearman at right back or centre-back, George Elokobi and Steven Ward at left-back now we have signed Van Damme.
"I am all for 25 players kicking, scrapping and biting to get into the team and making them as good as they can be."
Meanwhile, of the departing Iwelumo, Mick added: "Chris has gone. He was terrific. Lumes was one of the building blocks in the club's progress.
"You get sad but you have to move on. Players do become surplus to requirements.
"As a bloke I'd still want him around, but with regards to players they want to play football."
