Cristiano Ronaldo's camp are looking at possible options for the 36-year-old if he's forced to leave Juventus this summer, according to ESPN.
It's claimed that Man United, PSG and Real Madrid have all been contacted by the Portuguese's representatives to see whether any of those clubs will be interested in welcoming the forward.
Ronaldo is set to have a detailed discussion with new Juventus manager Max Allegri after the European Championship but at this stage, a move is not ruled out.
Any deal would be complicated, though: even though Ronaldo's deal with Juventus only runs for another year, the asking price could be a serious obstacle, as well as the player's wage demands.
As far as United are concerned, they have not ruled out signing a striker this summer, despite Edinson Cavani's contract extension.
It's not clear if they are willing to welcome Ronaldo back but they have time to consider it, as the ex-Red Devils will only make his decision after Euro 2020.
