The former England midfielder initially quit in 2011 but was persuaded to return for United in January last year.
However, the 38-year-old, who is expected to make his first appearance since January in Sunday's Barclays Premier League encounter with Swansea, feels it is time to bow out.
"Yes I am finally hanging up my boots for good," he said.
what a player he's been.
My disappointment was not seeing him deployed in his favoured role for England enough, shoved out to the left for Lampard and Gerrard for all those years that he called it quits early.
His club career however is unquestionable.
Absolute legend :')
