"We'd like some players who - in the 89th minute - don't lose the ball 20 yards outside the box which leads to us conceding a goal, which Tomasz Cywka did," Clough said.
"He's an extremely inexperienced and not very bright footballer. He should have chested the ball and hooked it into the corner flag with five minutes to go.
"That's what experienced, good players do in that situation. And despite being told - and he has been with us 10 months - he is still doing things like that. He can go back to Wigan or wherever he came from - I'm not really bothered - until he learns the game.
"It is getting very, very frustrating when you are dealing with people who are doing things like that.
"It's not a physical thing [with Cywka] - it's a mental one but if players don't learn then you move onto the next one."
