With 36 games to go, Derek has started with three compelling excuses:   'Defeat (2-1) not fair result' ,   'we are obviously disappointed that they have beaten us 4-0',   'individual mistakes were the difference between Ross County and Kilmarnock' ................beaten 2-1 again.   Who thinks next week it will be 'Dundee United edged it because they were smarting from their thrashing at Celtic Park'?
