REPLACING Callum McGregor when he is out through injury, as has been acknowledged by manager Ange Postecoglou, is a near impossible task. So it is also impossible not to feel for whatever player is indeed charged with filling his boots, and who will be judged using the Celtic captain as the yardstick.
That man would appear likely to be Oliver Abildgaard, who came on for McGregor when he limped off in the Red Bull Arena on Wednesday night. The Danish midfielder also has the added handicap in that task of not having started a game since May 21st.
After working hard on his conditioning since his arrival at the club on the last day of the summer transfer window though, he says he is ready to give everything he can to prove himself in a Celtic jersey. But he wants to do so on his own terms, and be judged as a player in his own right.
