Sarpsborg 08 sporting chief Bjorge Oiestad has confirmed the club have rejected offers for winger Sondre Orjasaeter.
Celtic reportedly submitted a bid for the 21-year-old which was swiftly thrown out ahead of the January transfer window closing at the start of next week.
The Sarpsborg chief has opened up on approaches for both Orjasaeter and Franklin Tebo as he insisted he is confident the pair will remain at the Norwegian club.
However, Oiestad did concede that there are "clubs out there that can turn around quickly" when discussing the duo.

"We have rejected several offers," said Oiestad. "I believe and hope Sondre Ørjasæter and Franklin Tebo will be Sarpsborg 08 players on Tuesday.
"But there are clubs out there that can turn around quickly."
According to Sky Sports, Celtic had a £4.6m bid for Orjasaeter rejected with Sarpsborg demanding a £7m fee to allow the winger to leave.
It's thought Celtic could return to the table with an improved offer being discussed.
In his press conference ahead of facing Aston Villa, Brendan Rodgers said of links to the winger: "I'm not aware of that at all. I don't know."
