Speaking to the Mansfield CHAD, ahead of this weekends game with Boston, Shirtliff said "This game has a nasty habit of biting you on the bum if you let yourself go a bit,"
"We are not safe. We need to win games - it's as simple as that.
"This six game unbeaten run has given us some confidence. But it's no guarantee of getting a result in your next game.
"We've won two and drawn four on this run and I'd prefer if it were the other way round.
"We have done quite well and we are making progress. But we need to get a bit tighter in terms of conceding goals and that's what we are working ont his week.
"We are by no means the finished article yet."
Meanwhile Shirtliff was delighted to extend Laurence Wilson's deal until the end of the season "I am pleased to sign Laurence for another two months.
"He has done well for us. I thought he played particularly well at Torquay and also made a good contribution at Notts County."
