Martin Cranie has featured in United's last seven games - all of which have ended with clean sheets.
The defender, currently out in Spain on warm weather training with his Blades team-mates, says the credit should be shared.
"It is brilliant for everyone connected, everyone is working hard, it is not just the defence who should get credit for it," said Cranie.
"That is what we pride ourselves on - keeping clean sheets, whenever we do we give ourselves a better chance of winning games and we have picked up a lot of points along the way recently, hopefully when we get back we get another one."
Speaking after a session in the sun on Tuesday, he added: "We seem to have trained more than we do at home, we had a hard session this morning. We'll now do a bit of recovery and hopefully there will be a bit of downtime for the lads."
