Simon Moore believes he's got 'England's number one' standing between him and a place in United's starting XI at the present time.
But the popular 30-year-old believes he and fellow stopper Michael Verrips, under the eye of goalkeeping coach Darren Ward, have played a big role in pushing Dean Henderson to the level of performance he's consistently achieved this term.
The experienced stopper, who joined United during the League One title winning campaign and established himself as Chris Wilder's number one for the vast majority of the 2016/17 season remarked: "There's at least two players for every position, everyone wants to be in the starting XI and it's just that the lads have been doing so well that the ones on the outside haven't really had a sniff.
"For me, I've got England's number one in front of me, I'm proud to be part of Deano's success, I'm always there to help him and advise him if he needs it. He's going to go on to have an incredible career and you can only have that success with having two players per position.
"I've been at football clubs where there is a bitterness of not playing. It's not an acceptance of not playing, everyone wants to be in that squad, but it's a case of I'm going to push him and if he does have a bad run of games, I'm going to be ready, but nobody wishes that on anyone, everyone just wants success for the football club and that's massive here."
Moore added: "I obviously knew Deano was on loan from Manchester United, so when the fixtures were out, I was looking for that one straight away (at Bramall Lane).
"I'll look back at that when I finish as a proud moment, but it's one that I don't really think about because I want to be successful, I want more and I want to squeeze everything I possibly can out of myself during my career.
"I've made my Premier League debut, what's next and that's the sort of person I am, you just want to work hard, do well and I enjoy seeing other people succeed too and I think we've got the same sort of characters in our dressing room to see others succeed but at the same time we've got that hunger and desire to be a better footballer and person as well."
