United's search for goalkeeping reinforcements is ongoing, confirms boss Danny Wilson, who has reserved special praise for George Long.
The 18-year-old Sheffield-born stopper has earned rave reviews since filling the void left by Mark Howard's thigh muscle injury but the Gaffer is adopting a cautious approach to Long's exposure, despite three strong displays:
"This run is endorsing what we think of George, he is a good prospect but we aren't getting carried away.
"We do feel George will progress into a very competent goalkeeper over a period of time, but people need to accept he will make mistakes. Sometimes we will get punished, other times we won't, let's hope he never puts a foot wrong, but that is highly unrealistic.
"George will become more confident and gain more experience with games, especially if he plays like he did at Notts County, he looked very assured throughout."
On the continuing hunt for another goalkeeper, Wilson added: "We are still looking around but we won't make a decision before the weekend.
"We need to bring someone in because we can't rely on young George (Willis), he isn't ready yet and that is with all due respect to his ability.
"George (Long) looks like he has matured into a man and is ready but we must remember he is still only 18-year-old too and we need some experience."
