The City Under-21s coach also praised the attitude and desire shown in the second-half after City claimed a point at Colchester United...
Coventry City Under-21s coach Darren Murray has demanded the first-half performance against Colchester United Under-21s 'must not happen again.'
The Sky Blues traveled to Colchester for their fourth game of the season, looking for their first win after impressive draws against Sheffield United and Swansea City.
The home side took advantage of a poor City start to go 2-0 up within the first 12 minutes, as Byron Lawrence and Macauley Bonne found the net.
Speaking after the game, Murray believes the start to the game always had City on the back-foot and says things must improve.
Murray said: "The way we started the game was not acceptable and it must not happen again. We need to make sure we're starting games much better than that.
"I said after the Swansea game that the first-half performance wasn't acceptable but I've just seen a worse first-half than that.
"It wasn't what we want to see and we expect much more from Coventry City. If you don't do your jobs properly in the game, then performances like that happen.
"We've got to press our lines much better and be aggressive in possession. I wasn't happy at the break and I made sure they knew that."
City rallied after the break and claimed a point at Colchester United thanks to a spirited second-half performance.
Shaun Miller, who played for 60 minutes, grabbed a quick-fire brace early in the second-half and Murray was happy with the response.
He added: "Billy Daniels had a late chance and if he puts that away, we win the game. The second-half is much closer to what we expect from this side.
"We just played on the front foot in the second-half and were much more positive with the ball. We didn't do anything particularly special, we just played at a tempo.
"We scored two excellent goals and to be fair to the players, they showed a lot of character to come back into the game which was good to see.
"However, I don't look for a 45-minute performance, I want a 90-minute performance and if we do that, we'll be winning these games."
