Varane, 28, was only ready to leave Madrid for United 10 years after rejecting Sir Alex Ferguson’s interest in joining the Bernabeu club, where Jose Mourinho was a coach at the time.
Varane has won three La Liga titles, four Champions Leagues, four Club World Cups and the Copa del Rey in a decade of wreaths with Madrid.
On her Instagram account, Varane wrote: “The last few days have been loaded with many emotions, feelings that I now want to share with all of you.
“After 10 incredible and wonderful years at Real Madrid, a club that I will always carry in my heart, the day has come to say goodbye.
“Since my arrival in 2011, together we have exceeded all expectations and achieved things that I could never have dreamed of. I want to thank all the coaches and all the people who work or have worked at the club for everything they have done for me.
“A big thank you also to all the Madridistas who have always given me a lot of affection and with their high standards, they pushed me to give the best of myself and to fight for every success.
“I had the honor of sharing a locker room with the best players in the world. Countless victories that I will never forget, including ‘La Décima’. I realize that it was a great privilege to have been able to live such a special experience of moments.
“Finally, I would like to thank all the Spaniards and in particular the city of Madrid, where my two children were born. This country will always be special to me. It was an incredible trip from all points of view. I leave with the feeling of having given everything and I will not change anything in this story which is ours.
“A new chapter begins …”
Varane will have to quarantine himself after arriving in Manchester before he can undergo a medical examination and complete his move. He accepted a four-year contract and the option of an additional year with United.
