Ronald Koeman wants Morgan Schneiderlin's future sorted soon after the Manchester United target missed the first day of pre-season training.
The Southampton boss said Schneiderlin was absent ill after consulting a doctor and insisted the player will join the club's upcoming trip to Austria.
Koeman also confirmed there have been no further bids for the midfielder since United had an initial approach rejected last month.
The Dutchman said: "Morgan's coming to train on Tuesday and will travel with the squad to Austria. There's a lot of speculation, but two weeks ago we had a Manchester United bid. It wasn't enough, wasn't serious, and there have been no more bids.
"Everybody knows the situation. I understand the player - if he can get a good move to a big one I can understand it.
"But I hope that if there is any business it will be soon, because it's best for the player and best for us. We have to prepare for what we'll do if we sell the player.
"I had a lot of meetings with Morgan - everybody knows his situation, but it's important for the player to do a good pre-season and we'll see what happens in the next few days."
Koeman also confirmed Saints' head of football development Les Reed is attempting to push through the permanent transfer of Toby Alderweireld from Atletico Madrid.
Southampton believe they have an option to sign the Belgium defender for £6.8m following a successful loan last year and say Atletico have missed a deadline for cancelling that agreement.
Tottenham are also interested, and Koeman said: "What happened with Tottenham in the middle I don't know. Les Reed is working on that situation and I wait for more news."
Asked if he still wanted the player Koeman added: "Of course, and the player told us the same before the summer."
