This is really funny honestly, I agree with you completely and also no club from outside the EPL will even pay £50m for Jackson with how he has been making a mess of himself since last season and the Saudi you talked about should have come knocking to get him since Chelsea have decided to sell him but up till now all we have been hearing are rumors and I don't see any club getting him for £80m not to talk of £100m, if I'm to be honest about this Jackson's issues and the amount placed on him, it will be a disgrace to those players who are worth the amount £100m and above in the transfer market if any club should get Jackson for that amount, not his type that should be placed with that amount.
The price tag is too high but that doesn't mean that Nicolas Jackson is a worthless player. He is strong and has pace, but he needs to play under a coach who can understand his weaknesses and help him correct them and improve on his strength. Chelsea is a big club and might not have such space to experiment and develop players. Moving to an average club might help build his confidence.
The Saudi Professional League targets players who are in good form, experienced, and popular. I doubt Jackson has such qualities now. He might end up going on loan or remain at Chelsea if the club fails to reduce his transfer fee.
Do you know that Jackson has already played for an average club well not that average before Chelsea? What I'm saying is that he has come past that level. He's suppose to be one of the best in the EPL when he arrives but he couldn't get things right even when the manager Enzo Maresca always see him as the best nothing impressive came out of him and you don't expect him to continue wasting chances and the manager continue to give him more time till the club stop competing for the EPL title, no it can't happen.
He has pace but he's always off color whenever he comes face to face with the goalkeeper like a one on one situation, Jackson doesn't have it at all so that amount should be reduced to maybe £25m because hebis the ine who reduce his value.
Like you said, Saudi clubs go for experience and players with good form, now Jackson doesn't have all of it and any team that spend that amount on him should go back and take their balance because he'll definitely continue making things hard for whichever club he finds him self.
I honestly want to be surprised when I see him banging goals and doing the impossible. Currently Manchester United have him on their radar but that doesn't mean they'll be happy to cash in on Jackson with that amount, his performance doesn't fit that amount.
