The players must take responsibility for United's poor home form in recent weeks, says Neill Collins.
The defender can understand the supporters' frustrations following consecutive home defeats at the hands of Hartlepool, Yeovil and, most recently, Coventry City.
On the slump at Bramall Lane, Collins insists the blame should rest solely with the players. He commented: "We can all talk about what has been going wrong, but as players it is down to us to rectify the situation.
"To lose three home matches on the bounce is always disappointing, but especially when you consider the opposition, and that is with all due respect. We should have beaten Hartlepool, without a doubt, given our respective league positions at the time and the same goes for the Yeovil and Coventry games, despite them both being in good form.
"We expect more from ourselves at home but for whatever reason it just hasn't happened of late and, as I have said, it is solely down to us (the players) to put things right."
Collins added: "Sometimes you can't put your finger on what is wrong, but now we have to look to the Colchester fixture, after two tough away matches, to returning to winning ways.
"We will only convince the fans we have turned the corner when we start winning games.
"If I was a fan I would be concerned, but they will believe in us again when we pick up a couple of victories and move forward."
