Paris Saint-Germain has already made a serious injury to Brazil's top player Neymar.
The Parisians on the last day of the transitional period will try to complete Willian's transfer to Chelsea.
The British daily, "Daily Mail", writes today that the Parisians are offering 45m euros for the London club.
In addition to William, PSG is about to complete the transfer of DC United's Luciano Acosta for ten million euros.
France's champion wants to become even stronger after taking Leandro Paredes from Zenit because Neymar expects a 10-week mandatory break after the metatarsal injury.
All this before the Champions League's first two matches against Manchester United.
Otherwise, the French champion is also interested in Arsenal midfielder Mesut Ozil.
