'All three goals were just given away and that is not acceptable.'
Leicester's defeat was more to do with the fact that the quintet of Lennon, Robbie Savage, Muzzy Izzet, Emile Heskey and Matt Elliott has been reduced by two.
So much of Leicester's success was down to them. But the famous five are no longer.
Of the remaining trio, Savage is unlikely to play much part in the rest of the season while Izzet played his first game since injury against the Sky Blues and Elliott came off at half-time with a groin strain.
It doesn't make particularly happy reading for Leicester fans to know that Junior Lewis, Damien Delaney and Lee Marshall are in the wings.
The Sky Blues, however, belied their position in the Premiership relegation zone with a performance of verve and attacking intent.
John Hartson's arrival has been the catalyst and Craig Bellamy is finding his feet out on the left - it was from his sidefoot that the visitors took a shock first minute lead.
Leicester hit back when Coventry keeper Chris Kirkland could only parry Arnar Gunnlaugsson's shot to Ade Akinbiyi, the outstanding Carsley headed a 19th minute second and the equally impressive Hartson nodded a third five minutes after the break.
