The 34-year-old Swedish striker, who retired from international duty after his country’s exit from the European Championship, said on his Facebook, Twitter and Instagram accounts that he will be joining United.
On his Twitter account, Ibrahimovic wrote above an image of United’s badge “Time to let the world know. My next destination is ManUtd.”
He would be linking up with former coach Jose Mourinho, who got on well with Ibrahimovic during their time together at Inter Milan.
