No. Your prediction of valuation doesn't take into account contract length and it's effect on transfer value and is also based on the assumption of a continual guaranteed improvement in the player's ability and form.He is 21 years of age 2 footed. This guy in 2/3 years will be a £150 mil player
He signed a 4 year deal in October 2023.
In two years time (2026) he will have one year remaining on his contract.
In three years time (2027) he will be coming to the end of his contract with potentially no transfer value whatsoever.
And before that there are any number of things that could go wrong as is often the case with young players. He's an excellent young defender, albeit a little overrated by some IMO, who I'd very much like to see in an Everton shirt for years to come. But thinking of him being a player with a genuinely realisable worth of £150M to Everton Football club in 2 or 3 years is borderline delusional.
