Coventry City manager Andy Thorn felt his side let Leicester City back in the match when they were down to ten men following the tenth minute dismissal of Darius Vassell.
Speaking about the game which Coventry lost 1-0, Andy Thorn told Sky Blue Player: "I thought we controlled the game for long periods of the first half and I felt we let them off the hook when they went down to 10 men.
"Even at 11 (men), I thought we controlled the game, when they went to 10 even more so.
"But that's a lesson we've got to learn, we dominated the game and through a lack of professionalism we let them back into it.
"But we've dealt with that in the dressing room and it won't happen again."
