Celtic have received a significant blow in their quest to sign Hammarby winger Sebastian Tounekti.
The Parkhead club have reportedly made multiple bids for the 23-year-old, who has scored two goals and set up a further five in 24 appearances for his side this year.
Brendan Rodgers remains on the hunt for attacking reinforcements before Monday's transfer deadline.

While Tounekti was an option, Hammarby's sporting director, Mikael Hjelmberg, appears to have blocked a potential move.
He said [Fotbolskanalen]: "I have informed Celtic and Seb that he will play for Hammarby this autumn.
"He took it well."
Hjelmberg was then asked whether he expects the Scottish Premiership champions to make another attempt at signing the player: "I don't actually know," he responded.
"I have received a few calls from them earlier in the day. I have been quite clear that our ambition is to keep Seb."
It comes after Celtic last night confirmed the acquisition of Marcelo Saracchi on loan from Boca Juniors for the season.
The Uruguayan could feature in tomorrow's trip to face Rangers at Ibrox, along with fellow new signing Michel-Ange Balikwisha.
