Juventus striker Cristiano Ronaldo could leave in the summer transfer window.
Ronaldo has scored 23 goals in 23 Serie A games this season.
According to Tuttosport, Real Madrid, Manchester United and PSG are all thinking of a deal involving the 36-year-old Portuguese.
However, a key problem in arranging such a move could be money.
All of these clubs would not be able to take advantage of the favorable tax rates that exist in Italy.
So, to sign Ronaldo, they will have to find other ways of attracting the player.
Meanwhile, at Juventus, the footballer receives €31 million after tax.
