Denis Irwin will quit Manchester United at the end of the season after 12 years at Old Trafford.
The former Republic of Ireland full-back, 35, has announced that he will seek a new club next summer.
Irwin, who signed a one-year deal this summer, said: "This campaign is definitely my last with United.
"I may play on beyond that elsewhere but it won't be here. You just know when it's your time and next summer will be it for me at Old Trafford."
