The Sky Blues have been held to a draw by Crawley Town at the Ricoh Arena.
Marc McNulty's second half strike brought City level and they came close to finsing a winner, but Harry Kewell's side held on to share the points.
"The first attack that they had, with any sort of intensity they managed to put it in the net which was really disssapointing and annoying," said Robins.
"The second half was a completely different game. The first half I thought we were really disjointed and we did not get enough of the ball or enough width from the full backs.
"That all changed at half time once we had gone back to a back-four. We started to create things and then grew in confidence then.
"Still, we took too many chances at times and ended up going direct. We made it 1-1 with a brilliant ball and an even better finish. Then there were some good balls into the area and across the box that could have gave us the win."
Robins' started the game with his side trying a 3-4-3 formation but were behind at the break thanks to a Jordan Roberts goal, forcing him to bring on Ben Stevenson at half-time and reverting back to a more familiar system.
"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 lackluster. 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 as 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.
He addded: "Missing Jodi Jones is a big thing but we have to come to terms with it, and it isn't just him it's Liam [Kelly] too.
"There are various things we can do and we were more fluid during that second half, but this team can be a lot better."
