Neill Collins says the five consecutive clean sheets the Blades have registered in recent weeks have been a real team effort:
"The clean sheet record of late is very pleasing for everyone, because if you aren't conceding goals you will always be picking up points.
"I am experienced to know, though, that in football you can never take anything for granted because this game has the habit of kicking you in the teeth.
"Sometimes you think you have defended to the best of your ability and you have conceded, other times you keep a clean sheet when you haven't been at your best, but we have thoroughly deserved the last five clean sheets.
"George (Long) has made a few notable saves, but he will be the first to admit he has been protected well by the back four, the midfield have helped the back four and the strikers do their bit too, we certainly defend from the front."
When asked if the Blades were gunning for revenge over the MK Dons at the weekend, Collins replied by insisting a win would purely be sought to improve our promotion ambitions rather than settling a previous score, after a controversial late penalty settled the corresponding fixture at stadium:mk.
The centre-half concluded: "Some people might think we might owe them one for inflicting our first defeat of the season back in November, but it isn't about revenge for us, it is about getting another three points to edge us ever closer to our ultimate aim - promotion.
"It doesn't matter who we are playing, all we are focusing on is the next game and adding points to our tally.
"MK Dons are a team that are capable of giving us a real tough game, but we are concentrating on trying to start the game well and put them on the back foot."
