"We thought there was a handball in the lead-up to the first goal but we can't concede two goals from set-pieces given the position we are in.
"We have to be brighter, uglier and meaner when we defend as a team. We want to play football but we have to do it in the right areas. " said the new City boss after the game.
With a trip to bottom side Scunthorpe United on Saturday coming up as well as home games against QPR (Wed Mar 5) and Norwich (Sat Mar 08), Coleman feels that City need four more wins to be safe from possible relegation.
"I'm confident that we can get the four more wins that we need to stay in this division."
