Mowbray has no case for his defence

TONY MOWBRAY warned Celtic’s stuttering defenders to “step up to the mark” after a jittery display ensured Rangers drew first blood in this season’s Old Firm rivalry.

Mowbray has tinkered with his centre-back pairing all season and for the trip to Govan he drafted in Glenn Loovens to partner Stephen McManus, with Gary Caldwell consigned to the bench.

However, Celtic, who have lost early goals to Hearts, Dundee United and Rapid Vienna in recent weeks, found themselves two goals down after only 16 minutes as former Parkhead striker Kenny Miller grabbed a double.
