I didn't know Juventus was still interested in Kolo Muani.

His Serie A performance wasn't bad at all last season. He was absolutely much more effective than he was at PSG. He could really be the worst deal ever for the French side as they bought him for 95 million euros...
Now his market value has dropped to 30 million. Juventus must have seen the opening there to go for him permanently.
16 games in Serie A with 8 goals is actually not too bad for a player who is starting to adapt in a new league so I think it could be fair if in the end Juventus still want to pursue Kolo Muani for the Juventus squad next season.
But borrowing back Kolo Muani now is clearly a little complicated because Juventus may not be too responded to, but if you really want to push then it's still possible.
Juventus know they need a striker especially at this time Dusan is clearly not too able to develop so in the end there needs to be a new option for Juventus in finding player options.
Now we just need to see if Juventus' efforts this time can go according to the will or even experience a deadlock considering PSG is clearly not a club that is too generous even though Kolo Muani also doesn't seem to be needed at PSG.
