Chris Morgan says skippering the Blades to promotion and representing the Club in the Premier League were two of the major highlights of his illustrious playing career in red and white stripes.
A serious knee injury sustained against Coventry City in October 2010 prematurely ended his playing career, but having announced his testimonial fixture will be against Newcastle United next month, the former captain insists he only looks back on his time as a player with so many fond memories.
Morgan, who made 279 appearances for United having joined from Barnsley in July 2003, feels the character and togetherness of the squad during the 2005/06 campaign was instrumental in winning promotion from the Championship under Neil Warnock.
Reminiscing, United's former number five said: "I have been lucky to be involved with this fantastic Football Club for approaching 12 years and although we have had a few downs, I will always remember the highs, you have to in football.
"We had some big personalities in the dressing room when we successfully won promotion in 2005/06 and you can't underestimate how important that was, it was a big part of the research Neil did on his players and everyone worked their socks off for each other.
"That togetherness and desire to win for each other can get you a long way in football, sometimes it can outweigh ability, but nobody would have argued that we didn't deserve to win promotion over the course of the season.
"I can still picture the ball nestling in the corner of the net at Cardiff's Ninian Park and we knew when Danny (Webber) scored that goal we were all but there and those memories are what you play the game for."
Unfortunately United's top-flight stay only lasted one season, but even after a cruel and controversial relegation, Morgan looks back on the season with some positive thoughts.
He added: "It is everyone's dream to be playing regularly in the Premiership, testing yourself against the world's best and for long periods of most games we competed well and did ourselves justice.
"In the end it was agonising and the tears of despair at the final whistle of the Wigan game were uncontrollable, but still we had a lot to be proud of."
Blades fans are reminded the game against Steve McClaren's Magpies will be played at Bramall Lane on Sunday 26th July, kick-off 1pm, with ticket news to be released in due course.
Morgan will also be donating monies raised from the game to three worthy charities, Weston Park Hospital, Bluebell Wood Hospice and the Gary Speed Trust Fund will all receive donations.
