John Egan believes the Blades excellent camaraderie is built on the majority of players coming from different openings into the professional game.
Speaking ahead of Saturday's trip to Millwall, the Irish defender remarked: "It doesn't matter whether you are Irish, Welsh, English or Scottish, there's always some banter flying round the changing room.
"It's a very, very close group and when we step onto that pitch it's about Sheffield United, it's good that we've got different backgrounds though and that's what makes us strong."
The three time capped international added: "I came over from Ireland at 16 and it's pretty difficult, a lot of players don't progress past their youth team, so I am proud of what I've achieved.
"I've had a few setbacks along the way, but I'm still improving and learning, and I still have a long way to go.
"If you come to England with the right attitude and work ethic it takes you far, but you have to have that ability too."
