After a rough start to life at Celtic, manager Ronny Deila appears to be turning the corner at Celtic Park, winning six of his last seven games.
One of the keys to their upturn in form has been the arrival of Manchester City striker John Guidetti, who has hit nine goals in ten games during his loan spell.
Yet whilst Guidetti is faring well at Celtic Park, the same can't be said of summer arrival Stefan Scepovic, who has scored just twice since signing from Sporting Gijon.
Rumours are linking Scepovic with an early return to Spain as Levante line up a January bid for the Serbian, and if that goes through, then Deila will need to sign another striker.
An interesting prospect could be a return to Glasgow for former Celtic goal machine Gary Hooper. The 26-year-old hit 82 goals in 138 games for Celtic during a three year spell with the club, before joining Norwich City last summer for around £5m.
Yet since the Canaries were relegated, Hooper has become a peripheral figure under Neil Adams, playing just 100 minutes - all of which have come as a substitute.
Rumours have linked Hooper with a loan move to Bolton Wanderers, who are managed by former Celtic manager Neil Lennon, but should Celtic look to bring him back?
Hooper's style of play would mesh well with Guidetti - Guidetti is quite a big, strong type of striker whilst Hooper primarily likes to live in the shoulder of the last man, using his decent pace to cause problems.
A proven goalscorer in Scottish football, Hooper could well be available in January, and if he is then Celtic need to gauge what it would take to bring him back to the club.
A potential Hooper-Guidetti partnership could be incredibly dangerous for Celtic, and opposing defences would have a hard time coping with them - and Deila should be taking note of Hooper's situation at Norwich.
