John O'Shea made his United debut in October 1999 in a League Cup defeat at Aston Villa. There have been periods since when he looked destined to leave Old Trafford, but approaching Saturday's encounter with Bolton, the Waterford-born defender has amassed 352 appearances for the Red Devils to more than justify his decision to stay.
"I don't want to look back on my Manchester United career," he said. "Fingers crossed there is lots more to come.
"I knew if I was going to leave United I would have a great grounding. The education was terrific, not only in terms of football, but maturing as a person.
"But when you look back, I guess everything has worked out okay so far. Long may it continue."
"It worries me," the 28 year old joked. "I used to think I was quite young. Obviously you know the years are ticking by because of the age of the lads coming into the squad and the amount of games you have played.
"I have been fortunate enough to be captain as well. You know you are maturing and getting that bit older."
"Overall, it is a good achievement for someone to stay 10 years at a club like Manchester United and to be involved in a lot of games and win some great trophies.
"Now I just want to continue and be a part of the team."
