Marti Cifuentes was left frustrated by his Leicester City side's slow start to their second half as they were turned over 2-1 by local rivals and Championship leaders Coventry City.
Jordan James struck for the Foxes within the first 10 minutes of their derby at the CBS Arena, but Coventry replied through an Ellis Simms effort - just 90 seconds after the restart - and then the Sky Blues claimed all three points through Haji Wright with just five minutes to spare.
After victories over West Bromwich Albion and Cheltenham Town in league and cup more recently, Cifuentes was hopeful of building on that positive form - but he considers the timing of Coventry's equaliser to be unacceptable.
