The club can confirm Robbie Brady has joined Hull City for an undisclosed fee.
The winger has impressed on loan at the Hull this season and last, and has now completed a permanent move to the Championship and signed a three-and-a-half year deal.
Brady, who officially became a Red in July 2008, made just one first-team appearance, in September 2012, coming on as a late substitute for Alexander Büttner in the League Cup win over Newcastle at Old Trafford.
The Republic of Ireland international, who caught the eye at full-back during last summer's pre-season trip to South Africa and China, enjoyed a spell on loan at the KC Stadium last season and impressed throughout his stay, so much so that he was invited back by the Tigers earlier this term for another temporary move.
That move has now been made permanent and everyone at Manchester United wishes him well for the future.
