The star of Celtic's season so far has undoubtedly been striker John Guidetti, who joined the Bhoys on a season-long loan deal from Manchester City on deadline day.
With ten goals in just 12 games for Ronny Deila's men, the 22-year-old centre forward has earned plaudits aplenty, as well as interest from the likes of Hull City and Marseille thanks to his goalscoring prowess.
Those goals have earned a call-up to the Sweden senior side, and after over a year out of the game with a mystery virus, everything appears to be heading in the right direction for Guidetti.
However, not everybody is quite so enamoured with him.
Former West Bromwich Albion striker Markus Rosenberg scored six goals in 33 games for Sweden, and whilst he failed to succeed in England with the Baggies, he's been prolific since returning to former club Malmo.
Rosenberg, 32, has now told Swedish press that his Malmo team mate Isaac Kiese Thelin is a much better prospect than Guidetti, and did more for the team during their time together in the Under-21 side.
"From what I've seen Isaac is much better," said Rosenberg. "Guidetti gets talked about so much without really doing anything."
"In those matches I saw the U21 national team, it's Isaac who has been considerably improved in all the matches that were shown on television. For me it is not possible to compare," he added.
Kiese Thelin is just 22 himself, and he and Guidetti are considered to be two of the hot prospects for the future of Swedish football.
Kiese Thelin also has two Sweden caps to his name already, but has scored just seven goals in 25 games for Malmo - a record far less impressive than Guidetti's is for Celtic.
