In his pre-match interview on Saturday's Sportsound, you could sense Stephen Robinson had been irked by the week-long reaction to the league defeat in Dundee as he led Aberdeen into the last eight of the League Cup against the same opponents. Yes, Dundee had opportunities, but the Dons were well worth their 3-0 victory that set up a quarter-final in Kilmarnock next month. Robinson will probably be frustrated this weekend's game at Fir Park has been postponed due to Motherwell's European commitments as he tries to build momentum in the league with the Dons' next outing against Rangers on Sunday week.
