Danny Wilson has once again praised the maturity of George Long, after seeing his goalkeeper keep five clean sheets in his last six matches.
Long, who has been the Blades number one since Mark Howard's thigh injury forced him off at Leyton Orient in October, has earned many plaudits since being thrown into the first team.
But a mistake in the defeat to Yeovil Town at Bramall Lane in January saw calls for the youngster to be rested, but Wilson says the way the Sheffield-born stopper has bounced back from that incident has pleased him immensely and will act as a learning curve for the future.
The Gaffer commented: "If George (Long) had been a midfielder against Yeovil Town nobody would have noticed his mistake that led to the goal. But as a goalkeeper you make a slip, the ball ends up in the net and you are castigated.
"From the inside we don't criticise anyone who makes a genuine mistake because you have to accept, with youngsters in particularly, it will happen.
"George is maturing brilliantly and the saves he pulled off against Leyton Orient shows how far he has come since breaking into the team in October.
"His concentration levels will get better, his distribution and decision making will improve too, but he needs games and minutes on the pitch.
"Thankfully he is getting an opportunity and George could go a long way to emulate what Harry Maguire has achieved in amassing 100 appearances at the age of just 19."
