Celtic are back in action this afternoon with another clash against their Old Firm rivals.

This time, the duo are both looking to secure a place in the Scottish Cup final.

The last meeting between the two Glasgow rivals saw Ange Postecoglou's side secure a 2-1 win at Ibrox in the SPFL earlier this month.

However, heading into Sunday's showdown, it seems as though the Hoops will have to make do without one of their key players.

What's the latest?

Speaking in his pre-match press conference ahead of the semi-final, Postecoglou revealed that striker Giorgos Giakoumakis will not be available to play as a result of an injury he picked up during Celtic's 7-0 win over St. Johnstone last weekend.

Since arriving at the Parkhead club during the previous summer transfer window from VVV-Venlo in a deal worth a reported fee of up to £2.5m, the striker has made 16 appearances in the SPFL.

In those appearances, the 27-year-old has found the back of the net nine times, with only Liel Abada (10) having bagged more league goals this season.

Postecoglou will be fuming

Having appeared in all three of Celtic's Scottish Cup games this season, the centre-forward has scored four of their nine goals against Alloa Athletic, Raith Rovers and Dundee United.

With that in mind, not only will it be a huge blow for the player to miss out on the chance to fire his team to the final this afternoon, but it is sure to have also left both Postecoglou and the Parkhead faithful fuming given how deadly he's been in front of goal.

To highlight how much of a danger the Greek international has been for his new club, he currently boasts the highest average of shots on target and goals per 90 minutes in the league, according to FBref.

Moving forward, with the Bhoys having Kyogo Furuhashi back in the frame after recovering from his hamstring injury, Postecoglou will have to hope that he and the rest of the attacking players at his disposal can make up for Giakoumakis' absence on this occasion.

Looking beyond that, everyone at the club will undoubtedly be hoping that the £1.8m-rated striker can recover from his injury soon enough to help his side see out the remainder of the season.
