Kolo Muani is currently at Juve's club World Cup, where he is loaded on PSG. After he joined the Bianconeri in January, it agreed that Kolo Muani could extend his loan until the end of the club World Cup.
Juve does not have a fixed option to permanently sign the French international, although PSG is open to negotiating a price.
But L'Equipe says that if Juve hesitates, Chelsea announces their interest.
It was suggested that Chelsea could sell Nicolas Jackson this summer and replace it with Kolo Muani.
Manchester United is also enthusiastic, although, unlike Chelsea, they do not yet contact PSG to register their interest.
