Coventry City manager Tony Mowbray has said that ultimately a defeat cost his side as they went down to a 2-0 defeat to Burton Albion at the Ricoh Arena.
Speaking to the Press Association, Mowbray said: "I said at half-time that the game may well be decided by a mistake and we must make sure it was theirs. We knew full well how hard they would be to break down and we had worked very hard on that since our game on Tuesday.
"Ultimately a mistake cost us. We had talked about concentration and if it had to be 0-0 then so be it.
"They are top of the league because they are very hard to beat. They make the game stuffy yet they look a threat on the break but we knew that and we have to accept what happened.
"First time we have lost at home and only the second defeat in 18 matches, so we have to stay positive."
