Reacting to yestesterday's news that he had secured Alan Sheehan for anther month, Shirtliff told the Nottingham Evening Post "Alan is a promising young player and he has done well since he came here. We're pleased to see him stick around for longer.
"I think he has enjoyed it here because he is playing in front of decent crowds instead of in reserve team football.
"He is also playing in competitive, rather than meaningless matches, where the standard is much higher and you are pushed that little bit more."
