Head coach Steve Cooper was left frustrated by a lack of competitive edge as Nottingham Forest suffered a second-half collapse against Arsenal.
The Reds were still in the game at the break, having settled after a shaky start which left them trailing to Gabriel Martinelli’s early header. But they were snail-like out of the traps in the second half and were blown away by three goals in the space of eight minutes.
Martin Odegaard went on to round off the scoring, adding to a Reiss Nelson brace and one from Thomas Partey to make it 5-0 at the final whistle. And it had been all too easy for the Gunners as Forest showed nothing like the fighting spirit which had been on display against Liverpool a week ago.
