The Sky Blues skipper was also disappointed that the positive first-half display counted for nothing as three second half goals condemned City to defeat...
Coventry City captain Jim O'Brien labelled the Sky Blues performance as 'naive' as they surrendered the lead to lose 3-1 to Doncaster Rovers at the Ricoh Arena.O'Brien was heavily involved in the game as he got the assist for the opener and was also close to a sending off in the first-half after two late challenges.
The captain admitted that his final warning by the referee did play on his mind in the second-half but he wasn't happy with the three goals that the side conceded and said they were all preventable.
"It's naive to think we can play for 90 minutes when maybe we should've turned them start of second-half," O'Brien said.
"It was a naive performance. They probably sensed our sloppiness in the second-half. Our first-half display was good and it was disappointing we couldn't capitalise on that. We deserved a little bit more with the chances we had, I think we were unfortunate not to be a couple of goals up.
"But to let a goal led slip at home is tough to take, they are all preventable goals, the first one we could have probably have made a tackle three or four times, myself included.
"After my warning from the referee after my first yellow card, the manager said to me to be careful at half-time. I was very aware of that, we changed shape and I went out to the right but I felt in my head it took away from my game."
O'Brien's wonderful pass for Samuel for the first goal was something that the side have been working on the training ground according to the skipper.
The 27-year old believes that the way the first-half went is a positive that the Sky Blues can salvage from the game and wants the side to bounce back against Peterborough next Saturday.
He said: "We'd worked on that in training so from the manager's point of view that's a real positive that we can take that from the training ground on to the pitch. We did a lot in the first-half when we were sliding passes for runners. But in the second-half we stopped running so that was disappointing as we worked on it in the week.
"Results say it is a struggle at home for us but we don't feel that way. We do have to be mentally strong when teams have a little spell in the game, we've got to see it out as a unit but things fell apart for us today. We need a response against Peterborough."
