Hertha Berlin boss Stefan Leitl has revealed he expects Celtic keeper target Tjark Ernst to decide his future this week.
The 23-year-old shotstopper is reportedly a key Hoops target for the new season and has a £4 million price tag on it, with his club keen for him to stay.
Celtic are in a battle with Wolfsburg to land the highly-rated former Germany Under 21s goalkeeper, with Ajax also linked.
Ernst returned to pre-season training this week in the German capital and Hertha have revealed there is plenty of interest in him, but remain hopeful he could stay with the Bundesliga 2 club.
Boss Leitl said: "Yes, of course I want as many players as possible to stay.
"But I think the situation is quite clear. There have apparently been offers for him.
"I believe Tjark is now in a position to make a decision. And we'll wait for that. And we have to prepare ourselves for either outcome.
"But I hope he stays."
And Hertha sports director, Peter Gorlich, conceded there was plenty of interest in the keeper.

He said: "I've been on the phone so much about Tjark that I've lost track of who was actually on the line!
"We are the player's contractual partner. He's still here.
"But of course, a goalkeeper like him, who already has such charisma at such a young age, attracts interest from other clubs.
"Tjark also knows what he has with us, what position he can play here in the future. We'll see what the various parties decide.
"This weighing-up of options is never easy. Firstly, we're talking about people and secondly, we're talking about key squad positions. And the goalkeeper is, after all, a crucial position.
"Nothing is ruled out, but we're prepared should certain scenarios arise."
