George Groves told Ringside that his eye-catching display against Carl Froch was not faultless.
Groves and Froch engaged in a titanic tussle for the latter's WBA and IBF super-middleweight titles in Manchester on Saturday night, which the Cobra won courtesy of a controversial ninth-round stoppage.
Groves was booed into the Phones 4u Arena but cheered once the bout had concluded after flooring Froch in round one and putting the Nottingham man on the back foot for a large chunk of the encounter.
The Hammersmith-born star maintains that his duel with Froch should not have been curtailed when it was by referee Howard Foster.
But told Adam Smith and Johnny Nelson that he did not execute his game-plan, fostered with the help of new trainer Paddy Fitzpatrick, to the nth degree.
"I systematically beat up Carl for nine rounds but I threw too many punches and could have been much more specific with my work, so my performance wasn't perfect, said Groves.
"But it was a damn sight better than Carl's, who looked very tired and, to me, never looked confident in the build-up, ring walk or fight."
Former Commonwealth light-heavyweight champion Nicky Piper joined Groves in the Ringside studio and echoed the sentiments of the Londoner, plus many pundits and punters, by saying he felt official Foster ended Saturday's battle too soon.
The Welshman - who fought Nigel Benn for the WBC super-middleweight strap in 1999 - believes that, on reflection, Froch may have recovered from his early knockdown and edged his British rival in Manchester.
But he says the Cobra should hand Groves a rematch, possibly in London, as the alternatives are few and far between.
"I feel sorry for both fighters because it wasn't the ending either would have wanted and I'm sure Carl would have wanted the chance to finish Groves off," said Piper.
"At the start of the ninth I thought Carl looked tired and that George would win but, in hindsight, you take into account Carl's powers of recuperation and think he might have won.
"However, this is a fight that would fill Wembley stadium and make an absolute fortune so why not do it again? The only other options [for Froch] are probably [Andre] Ward or retirement."
