Good luck to former Blades Kyle Walker, Harry Maguire, Gary Cahill and all involved with the England squad that will compete in the 2018 World Cup in Russia.
The Three Lions get their campaign underway against Tunisia on Monday and all three former defenders are in contention to be named in Gareth Southgate's starting XI.
Now 32, Cahill was the first to make his Blades debut, making 16 appearances on-loan from Aston Villa under Bryan Robson during the 2007/08 season, prior to a big money move to Bolton Wanderers.
Academy graduate Walker made a total of 37 appearances for his boyhood club, in two separate spells.
He made his debut at the back end of the 2008/09 season under Kevin Blackwell and played in the play-off final against Burnley, before departing for Tottenham Hotspur after just nine games a Blade.
But the following season, Walker returned on-loan from White Hart Lane and made a further 28 appearances for United.
Last but by no means least, is the leading appearance maker out of the trio and another Academy product, Harry Maguire.
The imposing centre-half made his Blades bow against Cardiff City at the Lane in April 2011, before going to make a total of 166 appearances in a red and white striped shirt.
Maguire left the Lane to join Hull City in July 2014 and enjoyed a terrific season at Leicester City last term, following a big money move to the King Power Stadium.
