Celtic correspondent Kieran Devlin says there have been complaints about the club's medical and sports science departments for 'years'. 

The lowdown

Kyogo Furuhasi, Celtic's top scorer this season with 11 goals, became the latest addition to the Hoops' injury list when he limped out of Thursday night's Europa League clash with Real Betis.

The Japan international sustained a hamstring injury, the same problem which befell Albian Ajeti against the La Liga outfit.

Christopher Jullien, Karamoko Dembele and Filipe Jota were already sidelined.

Manager Ange Postecoglou said after the game that his side were 'just going through a bit of a rough trot which never seems to end'.

The latest

In the comments section of an article published by The Athletic, a supporter argued that 'the sheer level and similarity of injuries in the squad is borderline professionally unacceptable', and raised concerns over 'the sports science, medical and coaching staffs'.

Devlin responded: "Don't disagree re: medical and sports science issues and it is feedback I've heard repeatedly over the years from sources close to players."

The verdict

Intriguingly, Postecoglou suggested on Thursday that the injuries may partly be a consequence of the players adapting to his demands on the training pitch and on matchday.

So it could be argued that he should reduce the intensity of the sessions at Lennoxtown to mitigate the risk - this injury to Furuhashi could, of course, cause real damage to their title bid.

However, the Australian also blamed what he called a 'ridiculous' fixture schedule and pointed out that the injuries would be less of an issue if Celtic had greater squad depth, so he doesn't appear to be overly introspective about the mounting injury plague.
