Ian McLoughlin is growing in confidence with every game he plays, says Dons boss Karl Robinson.
The stand-in keeper has played the last four games in the absence of injured David Martin, keeping two clean sheets as Dons sit second in League 1.
After a shaky start against Gillingham, which left Robinson to question the stature of his number two after conceding four at Priestfield, McLoughlin has made a series of top stops to keep his side in games, and is settling behind a solid defence.
“He’s in good confidence ahead of the game on Tuesday,” said Robinson. “You’ve got to feel for Ian because he’s come out of the cold.
“He has settled down after the Gillingham game. He got an awful lot of criticism after that, and he took it like a man. Hopefully, we’ll be looking forward to more clean sheets.
“There have only been 11 shots on target in the last four games, and our defence has performed wonderfully well.
“Ian has made some great saves in there too. There’s more positivity towards his performances.”
McLoughlin is set to keep his place in the team for Tuesday night’s visit of Chesterfield, though Martin could be fit for Saturday’s game against Preston North End.
