The City boss laid the blame firmly at the feet of his players and said to the media after the game: "I was embarrassed in the first half. "I'd like to apologise to the supporters for making the trip down to Plymouth, taking time off over the Easter weekend to watch that nonsense.
"Forget the second half. How many times have a team been 4-0 or 3-0 down at half-time and there's no goals in the second half?
"The game was done, it was over at half-time. It was an unacceptable performance in the first half.
"I am not happy about losing 4-0 or the fashion we conceded the goals."
