Clyne has put in some impressive performances under Ronald Koeman this season but as was the case last summer, good displays lead to links away from the Saints, and Clyne is believed to be worth around £15 million as he has just one year left on his current deal.
United and Chelsea have been linked with moves for the England international but the Red Devils have won the race to sign the 24-year-old defender if McDonnell is to be believed.
The Mirror journalist told MUTV: “United want him, what I’m told is it’s a done deal.”
If the deal is completed, Clyne will follow former teammate Luke Shaw to Old Trafford and the English duo could link up on either side of the United defence as they did so successfully at Southampton last season.

Brazilian full-back Rafael is looking likely to leave United this summer as he has just one year remaining on his contract and Louis Van Gaal will want to cash in on the defender after an injury-hit campaign.
Nothing has been confirmed by either club but the signs are pointing towards Nathaniel Clyne wearing a Manchester United shirt next season.
Would Nathaniel Clyne be a good signing for Manchester United?
