The Uruguayan forward has hailed the talents of the Real Madrid winger while maintaining that he hopes to stay in Paris until the end of his contract in 2018
Speculation surrounding Di Maria's future at Real Madrid has steadily increased after the July additions of Toni Kroos and James Rodriguez for a combined fee of close to €105 million.
Madrid have considered cashing in on the Argentina international - valued at €60m - in order to recoup funds for further transfer activity this summer, with Monaco striker Radamel Falcao on their radar.
Manchester United have also long been linked with a move for Di Maria, although PSG are believed to be in a stronger position over a deal, and Cavani admits he would relish the chance to link up with the player at Parc des Princes.
"We are always looking to add new elements to the team," said Cavani to L'Equipe.
"[Di Maria] has a lot of quality, is a fantastic player and he would be welcome in Paris."
The 27-year-old, whose contract runs until 2018, also went on to confirm that he was not looking for a move away from Paris, but hinted that it was ultimately down to the club.
Cavani is another player to have been linked with United in recent months, with PSG under pressure to limit their financial losses this summer due to Financial Fair Play sanctions and having already spent €50m on David Luiz.
