Callum McGregor is irreplaceable for Celtic and they have a dilemma on their hands to see who can fill the captain's void, according to James McFadden.
The midfielder has been spotted in a knee brace following being taken off with a knee injury during Wednesday's 3-1 Champions League Group F loss to RB Leipzig. He was already suspended for today's lunchtime meeting in the Premiership with St Johnstone after a red card against Motherwell last Saturday and manager Ange Postecoglou has said it's not going to be a short-term issue for McGregor, who is awaiting the results of a scan to determine how long he's out for.
He is a leader on the park but former Scotland international McFadden insists his work in helping Celtic build play from back to front is pivotal. Key centre-back Cameron Carter-Vickers is on the injury comeback trail but his return comes alongside the loss of another crucial player. McFadden told Open Goal: "It's mad because you've got (Cameron) Carter-Vickers potentially back.
