TONY Mowbray failed to hide his disappointment after watching his Sky Blues side throw away a 1-0 lead at home to Doncaster Rovers on Saturday.
Dominic Samuel had given the Sky Blues a narrow one-goal advantage at the break but three second half goals from Richie Wellens, Jonson Clarke-Harris and Harry Forrester gave play-off chasing Doncaster the win at the Ricoh Arena.
The defeat leaves the Sky Blues sitting just one point away from the League One relegation zone.
And although Mowbray revealed the recent rigorous schedule may be taking its toll on the side but the manager is not using that as an excuse.
“Individual errors have cost us,” said Mowbray. “It was the same in the Port Vale game where the same occurred. I’m trying to implement a system where players won’t become isolated so that can happen.
“We paid the price. Credit to Doncaster, they were a decent team and they’ve done well.
“I’ve said before let’s not get carried away, things can’t change overnight and we’ve had a reality check.
“I took Adam Barton off at half-time because I thought he was fatigued. He’s played a lot of football since I’ve been here and I thought he struggled through the first-half.
“Jim O’Brien who missed out a few weeks ago as he was tires and picked up a niggle. I didn’t want another Marcus Tudgay situation with a muscle injury so I took him off as a precaution.
“I’m not making excuses and I don’t want to as there are none for that second half performance but a number of players are tired.
“We now have to go again against Peterborough and get back to winning ways.”
