"Something that I did not expect was to be 4-0 up at half-time. We have got a home game plan and the boys have worked very hard at it.
"I think we showed in our last home game against Burnley signs of what we can do, even though we did not get a result
"Today all their hard work and endeavour paid off. They won at Blackpool, which was an important result for us, and now - with two home games come in the last four - we have got an important home win."
Coventry boss Chris Coleman was shell shocked.
"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."
