Feyenoord have reportedly made an offer for Manchester City striker John Guidetti.
The 22-year-old Swede is currently on loan at Celtic, where he has scored 14 goals in 32 games.
However, his contract with Premier League champions City is due to expire at the end of the season.
Dutch side Feyenoord have now lodged an official approach for the forward, according to Sky Sports News.
Celtic boss Ronny Deila has repeatedly claimed that he would like to sign Guidetti on a permanent deal in the summer.
The youngster spent the 2011-12 season on loan at Feyenoord, scoring 20 goals.
