Derek McInnes admits today's defeat to Rangers was disappointing – and reckons the second goal was harsh on his side.
Gio van Bronckhorst's side bagged a 2-0 Premiership win over Kilmarnock thanks to second-half goals from Antonio Colak and Alfredo Morelos.
The Ayrshire side did well to keep out the Light Blues for the opening 45 minutes, but in the 51st minute, Colak found himself through on goal and he made no mistake in firing his effort across Sam Walker.
