Yes, it is very possible because it is unlikely that Real Madrid will be willing to spend a lot of money to recruit Osimhen from Napoli because their target is Mbappe.
But the Mbappe transfer drama is very long and Real Madrid really need a striker to replace the position left by Benzema, this is a little difficult I think.
Napoli don't seem to want to let Osimhen go, that's why they set a high price. In my opinion, it's really not worth it for Real Madrid to sign him and I think it's better to wait and keep chasing Mbappe.
We can no longer link Osimhen with Real Madrid because Madrid are sure to get Mbappe because the news is they have reached a secret agreement so they won't spend a lot on a striker, the only chance of Osimhen moving is the Premier League but so far not a single club has negotiated. Liverpool are rumored to be trying to approach him but so far only rumours, it looks like Osimhen will continue to play in Serie A next season exactly what Napoli hoped for. Maybe Napoli's finances are fine so they don't need additional fresh funds.
