Mark Robins felt his side were well worthy of their point after Saturday’s 1-1 draw at Sunderland.
Defender Dom Hyam had put the Sky Blues in front in the first half and Robins was pleased that the work on the training ground had paid off.
Robins said: “Yeah the set piece is something we have worked on in the training ground and we don’t score enough from them, we have good quality and the delivery was better today.
Despite the point, Robins admitted that his side could have managed the game better in the second half.
He said: “The conversation we have just had in the dressing room is around communication.
“The difficulty you have with it is, you have very inexperienced players playing alongside experienced players and those experienced ones have got to take control of the situation.
“We could have dealt with the situation better when they scored the goal because we weren’t in the position from throw in, then we were stretched, we dropped deeper and panicked.”
Robins stuck with the formation that he first used against Colchester in the FA Cup and has been pleased with the adaptation the players have made.
Robins said: “It isn’t all going to be perfect, we have only played the formation 4 times and haven’t had the time to work on all eventualities with it but the majority of the games we have played with it, including today, it’s been pretty good.
“We were playing back to the goalkeeper and trying to take the sting out of the game which is alright at times but it was too early to do it.
“Then what happens psychologically, you drop deeper and deeper and we have got to do better than that.
“Keeping the ball that’s fine but we need to have a purpose about it, they got back into the game when they shouldn’t have and we should have killed the game off.
The point means the Sky Blues sit fifth in the Sky Bet League One table and Robins feels that his side have even more to give.
He said: “You can see that there are elements in the game that are outstanding but some that were just not there today.
“One or two things weren’t right and we can get better at it, but we can take the point as a positive and keep working and making it better and stronger.”
