Mbappe does have a high value at the moment the contract at 200M is still very possible especially now that Real Madrid is still eyeing him until his contract expires. Let's see how Real Madrid make a special offer to Mbappe.
His current market value is about €180m, it is lower than the price was in 2018-2019 when the price reached €200m. Mbappe gets difficulty to show his best form this season, it is decreasing a bit. It makes sense if his market value is decreasing to €180m.
Real Madrid will pay 0 money if he signs Mbappe after his contract expires. This is actually what Real Madrid is waiting for in the next year.
Of course, the market value will decrease because currently Mbappe cannot achieve success like the 2018/19 season, which led France to win the World Cup and Mbappe won the title of best youngest player.
Now with PSG he doesn't get anything except the Ligue 1 title.
This is an opportunity for Real Madrid because they will only have to pay salaries without having to pay more like PSG asked for last season.
I don't know if the 150M for Osimhen will go to Chelsea this is just a rumor while Real Madrid will not prioritize the Napoli player, while for the Arab club Osimhen there is no interest there.
Osimhen must move to a team that can offer him the chance to win trophies. I doubt if he wants to move to Chelsea although Chelsea can pay him more expensive than other teams. Chelsea is just a mediocre team in EPL, Osimhen won't expect any trophy with Chelsea.
But if he only plays with Chelsea then Osimhen will still have no chance of winning any title considering that Chelsea condition is really impossible.
If Osimhen really wants the title then he can go with team that has great potential.
However, we can see that there is lot of news that Osimhen has agreed to the contract extension that will be carried out by Napoli.
