Daley Blind's return to Ajax moved closer on Monday night as Manchester United agreed terms with the Dutch club.
The 28-year-old Holland international swapped the Amsterdam giants for Old Trafford four years ago in a £14million deal.
Blind made 141 appearances for United over that period, but only played seven Premier League matches last term for Jose Mourinho's side.
And he is now set to head home, with United writing on Twitter: "#MUFC has agreed terms with Ajax for the transfer of @BlindDaley. A further announcement will be made in due course."

A deal worth an initial €16m is understood to have been agreed. Add-ons could see the fee rise to €21m.
Blind wrote on Twitter: "I want to say how proud I am to be a part of the Manchester United family. To play for the biggest club in the world with such a history meant a lot to me. I had 4 great years with 4 trophy's!
"I want to thank you for all the love and support I received and still get. I will never forget some of the special games and moments, I will miss you 'The Theatre of Dreams'! But now its time to go home."
The Dutch side have already signed Southampton's Dusan Tadic this summer and landed in England for a pre-season training camp on Saturday.
Blind would be United's first high-profile sale of the summer, although captain Michael Carrick retired and joined Mourinho's coaching staff.
Highly-rated Porto full-back Diogo Dalot, Shakhtar Donetsk's Brazil international Fred and veteran Stoke goalkeeper Lee Grant have all joined United this summer.
