Brady to make a call between goalkeepers as Chukwuemeka is told what he must do to earn more game-time
Striker has only made two brief cameo appearances since Brady took charge
Jon Brady will make a decision on whether or not to recall goalkeeper Steve Arnold to the team for Tuesday's game against Plymouth Argyle following his criticism of Jonathan Mitchell at the weekend.
Mitchell, who has started all five games since Keith Curle left the club, was at fault for both Swindon goals on Saturday, failing to keep out Scott Twine's free-kick and then caught out of position when Brett Pitman headed in the winner.
Arnold's last appearance came before Christmas and Brady revealed on Saturday that he has been struggling with a back injury despite being fit enough for the bench.
On who might start against Plymouth, Brady said: "I can only repeat what I said on Saturday. Mitch knows he should do better in those positions.
"I went through it after the game on Saturday and we have discussions and we work with the goalkeepers.
"We go through what they can do better and how they can do it better. We've gone through that and whoever we pick on Tuesday will do their utmost to keep a clean sheet."
Meanwhile, academy striker Caleb Chukwuemeka has only been on the pitch for a total of 25 minutes across Brady's five matches in charge.
Town's caretaker boss worked closely with the 19-year-old when he was head coach of the youth team but does not believe he is ready for regular minutes despite the team's struggles in front of goal.
He added: "Caleb has got a lot of good qualities and I know that because I worked with him, but he needs to work a lot harder off the ball and out of possession.
"He needs to make sure that, as soon as we lose possession, that's one of his first thoughts - to work hard off the ball.
"For him to improve, he knows that needs to come more naturally to him than what he's delivering at the moment.
"But he is an asset for us going forward if we can get him the ball."
On Alan Sheehan, who trudged off after just 25 minutes at Swindon, Brady said: "Alan has gone for a scan so we're waiting back on the information to see where he's at, that's the situation at the moment."
