The Celtic forward's agent wants a move for his client sooner rather than later.
Teemu Pukki's agent admits transfer talks are currently 'a bit frustrating' as there has been no word from Celtic as to whether his client can join Brondby on a permanent deal, according to Danish site Ekstra Bladet.
The 25-year-old was sent to Brondby on loan and recent speculation has linked him with a full-time move to the Danish side, with the striker happy there and Celtic seemingly happy to let him go.
But Pukki's agent has spoken of a growing frustration from within his camp, as the player simply does not know where Celtic stand.
A fee has to be agreed by both clubs, the representative says, and he would prefer a move for his client sooner rather than later as Pukki's last three transfer moves have all occurred late in the transfer window.
Teemu Turunen told tipsbladet.dk: "I cannot say much, because right now it is not in our hands. He has enjoyed his time in Brondby and he really likes the club but the situation is that we do not know what Celtic will do. He has a contract with Celtic, so they determine what should be done.
"We really want to find a solution for Teemu but the truth is that the two clubs must agree on a price before we can do anything.
"But there should be no doubt that I hope we will soon have clarity because Teemu's last three club changes have happened late in the transfer window. It is better if he could change early.
"When we know what Celtic want, it will make it all work much easier. Right now, I do not know what happens next week or next month and it is obviously a bit frustrating because we want to work hard to find a solution that suits all parties."
There will no doubt be more ins and outs at Parkhead this summer, with former Manchester City defender Dedryck Boyata being unveiled as Celtic's latest signing on Tuesday afternoon.
Pukki looks as though he won't be with the Bhoys for much longer - if they can agree numbers with Brondby.
