Adam Murray said young keeper Sasha Studer had ‘become a man’ in the past week after helping Stags all but achieve League Two survival.
He also paid tribute to the work done by goalkeeping coach Billy Turley in helping the 23-year-old Swiss stopper start to blossom.
“Billy Turley came in as goalkeeping coach a few months ago and has worked hard with Sasha,” said Murray.
“A lot of people dismissed Sasha, but he is a baby as a keeper and had never played League football.
“He’s not been in the best environment in the situation we’ve been in. As a keeper, it’s a pressure position. It’s a tough one with the manner of goals we’ve been conceding this season. You have to organise your back four and everyone in front of you.
“Billy has worked really closely with him and I have seen a change in Sasha, not just as a keeper but as a person. I think he has matured and become more of a man.
“He has that hunger and he is very ‘out there’ as a character which I like.
“But he has become a man over the last few weeks and I am over the moon for him. A lot of credit for that has to go to Bill.”
