Mark Howard says he refuses to take his place in the team for granted, despite keeping 14 clean sheets since returning to the team at Fulham in January.
After reclaiming the number one jersey at Craven Cottage, the Blades won ten matches on the spin in all competitions, but Howard insists the success wasn't purely down to his recall.
Speaking ahead of Tuesday's clash with Oldham Athletic, the 27-year-old remarked: "Of course as a goalkeeper I pride myself on keeping clean sheets, but it isn't just down to me, our revival since the beginning of February has been a real team effort from back to front and thankfully I have been fortunate enough to be apart of that run.
"George (Long) is a tremendous young goalkeeper with a very bright future ahead of him and there is nothing to say that he wouldn't have kept the clean sheets too.
"We are both desperate to play on a regular basis and that is good, healthy competition. We are good friends, we both have different attributes and we are always trying to help each other improve.
"I pushed George as hard as possible earlier in the season and now George is repaying the favour, he works tirelessly everyday on the training ground and that benefits the whole group.
"I am fighting hard to regain my place and George is trying to force his way back into the starting line-up."
