Respected Dutch newspaper De Telegraaf report that Ibrahimovic will join United this summer on a free transfer from Paris St-Germain.
It’s said he will start his Old Trafford career as a player before moving into a role as coach under Mourinho.
United have yet to confirm Louis van Gaal’s sacking, yet alone Mourinho’s arrival to replace him.
But De Telegraaf are close to Ibrahimovic’s agent Mino Raiola and the news isn’t believed to be idle speculation.
The piece, which was published this afternoon is headlined “Ibrahimovic to Manchester United”.
