PSG are also ready to make a £70m offer for Arsenal forward Alexis Sanchez, 28 and offer him £400,000 a week.
Alternatively, PSG will make a £35m offer for Alexis Sanchez next week.
Alexis Sanchez and his representatives were in Paris on Friday to meet with Paris Saint-Germain sporting director Antero Henrique.
Henrique and his assistant travelled to the United States with PSG last weekend but returned to Europe before the club’s International Champions Cup opener against Roma in Detroit because of urgent transfer business.
According to the source, that transfer business concerns Sanchez and Neymar, and Henrique swiftly moved to London after his return to Europe.
Henrique’s flying visit to London was fruitful as he then received Sanchez and his representatives, including agent Fernando Felicevich, at Le Royal Monceau in Paris.
