As with any manager, Celtic boss Ronny Deila has had his fair share of hits and misses in the transfer market.
John Guidetti was certainly a hit before his mini-goal drought, whilst goalkeeper Craig Gordon, centre back Jason Denayer and striker Stefan Scepovic are proving their worth.
However, some have struggled. Ghanaian winger Mubarak Wakaso has made virtually no impact, whilst Aleksandar Tonev has been embroiled in a race fiasco with Aberdeen defender Shaleum Logan.
Yet the most disappointing of Deila's summer signings may well be Norwegian playmaker Jo Inge Berget, who was reunited with Deila, his former Stromsgodset boss.
Berget, 24, joined Cardiff a year ago, following his Molde manager Ole Gunnar Solskjaer to South Wales, but played just twice before being completely frozen out by new Bluebirds boss Russell Slade.
A move to Celtic was obvious; it gave him the chance to go and play under one of his former managers, and in Deila's 4-2-3-1 system, there was a role for him.
Even after scoring twice in four league games, Berget found it difficult to play regularly and remarkably, his loan spell was cut short earlier this month, with just eight appearances to his name.
Cardiff see him as being surplus to requirements and have even allowed him to train with Norwegian side Honefoss ahead of a possible transfer.
A return to Scandinavia was always likely, and whilst Berget says that no move to Honefoss is immediately possible, he could make the move if he impresses in training.
