Blues chief Jose Mourinho is rumoured to be ready to spend in the coming months after watching his side narrowly miss out on a Premier League and Champions League double, and it thought to have funds in place to do so.
One player he is keen on is Lavezzi, who could be free to leave the Parc des Princes during the next transfer window.
PSG have recently agreed a potential £50m swoop for David Luiz, and it is understood that the Argentine forward’s name came up during discussions between the clubs.
Chelsea are believed to have enquired about ex-Napoli man straight after dispatching of the Parisians on their way to the last four of Europe’s top club competition, and are still keen on him.
With the realities of Financial Fair Play set to hit PSG, the sales of some top stars may be needed, and Lavezzi is one who may be deemed expendable.
However much depends on Oscar’s future.
After starring for Mourinho during opening half of the campaign just gone, the Brazilian playmaker suffered a dip in form.
Offers of around £40m may well be accepted by the Londoners, who paid £20m for his signature a few years ago.
