"I am very close to signing a new four-year deal and, fingers crossed, that will be done and dusted before the start of the season," said O'Shea, whose present contract expires next summer.
"That will take me to around 27 or 28 years old, which people say is around the time you reach your prime. Overall, I am looking forward to spending a lot more time at United and enjoying lots more success."
The 24yr old player is hoping to become a major part of Alex Ferguson's plans for the new season following the recent departures of Phil Neville and Kleberson he can expect to be involved on a more regular basis.
“When I first broke into the squad I played about 50 games a season for a couple of years," he said.
"Last season I took part in 37, so anywhere in between would be nice."
