Coventry City manager Mark Robins said that more work will be needed on the 3-4-3 formation that he used in the 1-1 draw against Crawley Town.
Speaking to BBC Coventry & Warwickshire about the game which saw Jordan Roberts give Crawley a 41st minute lead before Marc McNulty snatched a point for City in the 73rd minute, City boss Mark Robins said: "We have to try and do something. We have the personnel to play that system but we need time to work on it, and after today we need to work on it a lot more.
"It looked a bit lacklustre. I think three games in a week is a big test for us. We had a few fresh faces and fresh legs by the end but this game suited an extra midfield player which is why I brought on Ben Stevenson. His passing was brilliant today.
"There are postitives though. It was a great finish from McNulty. That goal will do his confidence the world of good. That was a real strikers goal. I think he is reluctant to count any goals that go in off his backside or ones that he just taps in, when he should because he is a really good striker. He is just starting to get going now.
"Jordan Ponticelli was unlucky with one chance, and Duckens Nazon hit the post in the first half, during what was a positive start but the goal set us back."
