City manager Steven Pressley has also reassured fans the club will sign players before Friday's deadline...
Coventry City manager Steven Pressley has said it's likely striker Leon Clarke will leave the club in the January transfer window.
The Sky Blues suffered a 2-0 defeat to Leyton Orient at the Matchroom Stadium as Dean Cox and David Mooney scored second-half goals.
Clarke missed the game with a foot injury and the City manager described his disappointment with the forward after the game.
Pressley said: "Leon Clarke has failed to support this group. The situation has changed over the last 24 hours.
"It looks likely that he will leave the club. He gets his wish. He has behaved in a manner to get his move.
"I am annoyed as I have got a group of players who are putting everything in for the club and they have been let down.
"It's football but it isn't what I agree with. This football club has helped him get to where he is. Sometimes, players leave but there is a way to leave a football club."
With Callum Wilson set to be out for another four weeks, Pressley says the club are 'working tirelessly' to get players in before Friday's deadline.
He added: "We are continuing to work hard behind the scenes to get the right personnel in. We haven't stopped working.
"I have got the support of the owners to bring in good quality and that's what I want to do.
"We thought we'd have a few in already but it didn't come off. We have to keep going and I'm positive we will have some players in the building before Friday.
"We need to help this group as they are giving everything for the club."
