Celtic have been dealt a huge injury setback ahead of their upcoming Scottish Premiership clash.

What's the talk?

That's according to a report by The Scotsman, who claim that Ange Postecoglou's Celtic side will be without at least seven first-team players for the trip to St. Johnstone on Sunday, with David Turnbull, Jota, Albian Ajeti, Giorgos Giakoumakis, James Forrest, Karamoko Dembele and Christopher Jullien all looking to be sidelined due to injury.

A further report by the same publication went on to state that both Joe Hart and Kyogo Furuhashi - who missed the 0-0 draw against St. Mirren earlier in the week with knocks - could also miss out at McDiarmid Park this weekend, as the duo do not appear to have recovered from their respective injuries.

Postecoglou will be fuming

Considering the sheer number of injuries he is having to deal with at present, the news that none of his previously injured players look set to make a return to action this weekend, while both Hart and Kyogo also remain doubts for the fixture, is sure to have left the 56-year-old manager fuming.

Indeed, should attacking midfielder Turnbull, left-winger Jota, centre-forward Kyogo and goalkeeper Hart all be missing on Sunday, the Greek-Australian coach would be unable to select his best, fifth-best, 10th-best and joint 13th-best performers respectively in the top flight of Scottish football so far this season - of players who remain within his first-team squad.

And, when taking into account just how much Postecoglou's depleted Celtic side struggled to break down St. Mirren on Wednesday evening, should the manager once again be unable to call upon any of the aforementioned players, it would not appear to bode well for Celtic's chances of picking up all three points against Callum Davidson's side.

This could potentially bring disastrous ramifications to the club's Premiership title hopes this season, as dropping more points on Sunday could well see the Bhoys fall further behind their Old Firm rivals - who currently top the league standings by six points.
