Another problem with 100m players is that you can never get that value back in the market, in recent times the only players who would have gotten their values back would have been Mbappe and Haaland and even with that, both clubs (RM and us) were smart enough to not go in with that type of money for these players.
A 100m player is a lifetime commitment to that player, so if you're lucky enough and win the lottery on that signing, great, but if not then you're stuck with that player, at which point you can either sell the player for half the value or just stick with the player until their contract runs out and then release the player for free, incurring a huge loss. I'm just happy that during Jack's time here, we have won the UCL and the PL, so that at least makes him look like a good signing on paper.
All in all, I don't think there's a 100m player in the market right now....maybe Mbappe, Haaland and Vini and even that's up for debate
