PSG are making it a habit of discarding good players and I don't know the reason for letting this player Kolo Muani go on loan in the first place but one thing I believe is, he would have made an impact with the PSG side last campaign but Juventus had that opportunity to strengthen their attacking department which Kolo Muani showed every bit of himself. As it stands, Juventus need to grab this opportunity with both arms because in no time I expect other clubs who are desperately looking for an attacker to step up and get him after all he did last season and also in the just concluded FIFA Club World Cup. This player is not the type that needs to spend much of his time on loan, they need to take him serious come next season.
Opportunities they say don’t always come by and Juventus have a golden opportunity on their hands to sign striker Kolo Muani permanently from PSG who are willing to sell this summer. As you said he shouldn’t cost much, I keep wondering why Manchester United that are desperate to sign a striker don’t consider such a player over Sesko that would cost them a fortune.
There are also reports of United's interest in Kolo Muani. But I am confident that if negotiations with PSG go smoothly, Kolo Muani will be in Juventus's hands. I believe United will not have much hope of winning the battle in this transfer window, unless they are really willing to compete by spending a lot of money. But I am sure United will not do that for now. They will still be the same team as last season, with not many changes.
