Injury depleted squad meant City were left short, as Rochdale claimed all three points at Spotland...
Sky Blues boss disappointed with 'disjointed' Coventry City performance, as Dale striker Ian Henderson fired his side to three points.
Netting his 18th and 19th of the season, the 32-year old was on target either side of half-time to secure the home victory.
Mark Robins said: “It was always going to be interesting to see what reaction and what performance levels we were going to get out of the players.
“We’ve had to make changes through injury, lost a couple more today. Ben has come off with his neck, I don’t know the extent of it.
“The power of the Rochdale players compared to ours was noticeable, it teaches me, underlines everything.”
City have two games of the League One campaign remaining, after accepting their fate on Good Friday against Charlton. A home fixture against Walsall is the club's penultimate tie, before an away trip to Scunthorpe.
Robins added: “I think Rochdale are a good side, Ian Henderson typifies what is good about them. We were short in the defensive department first-half, disjointed performance, but not unexpected with the changes we’ve made.
“Their midfielders know the game, they can mix it, play when they need to. It is two games from the end of the season, I want to get on with the job.
“It is disappointing but not something that I expected, it is in the players and reared its head again today.”
