PSG chief Leonardo wants to bring Manchester United striker Dimitar Berbatov to France in 2011.
Berbatov is off contract in June and if United refuse to sell in January, Leonardo will push to secure the Bulgarian to a pre-contract ahead of a Bosman move at the end of the season.
French sources say Leonardo has made Berba's capture a priority and will test United's resolve in January with an offer of £8 million.
PSG have just extended the contract of Mevlut Erdinc to 2015, but Leonardo also wants Berba.
