Andy Walker has suggested that Celtic duo Anthony Ralston and Yuki Kobayashi will have a plethora of eyes watching their every move when the Hoops travel to Ibrox on Saturday lunchtime.
Celtic haven't lost to Rangers in eight league meetings, with their previous downfall on Govan soil coming in Ange Postecoglou's first ever Old Firm derby. Such is their dominance, that Rangers' only win over the Hoops since then was in last season's Scottish Cup semi-final. And having not lost at Ibrox in their previous two attempts, Postecoglou will be looking to make it a hat-trick without losing just south of the Clyde.
But Cameron Carter-Vickers, widely considered as Celtic's best defender, and Alistair Johnston, who picked up a Man of the Match award in his last league outing against the Gers, are both out of action - which could throw a spanner in the works for Postecoglou.
