Man U paid £60M for a 19yo Anthony Martial & that was 3 seasons ago, so given market inflation, what’s that, 100? 150???  Nobody would say that was a bad deal now.
As others have said, it’s all about the player & whether they can help us win games (which generates money).    When we were after Williams, I didn’t want him at any price.  The £12M just added insult.   Very much the same with Bolasie & Klaasen.   I didn’t want us to sign Sigurdsson (good player, but not what we need) & the £45m just ridiculous.   Richarlison is EXACTLY what we need.   Big, strong, fast, skilful, direct, exciting.   £35m seems a very fair price & if we have to pay the add-ons, he’ll have delivered.
Can’t wait to see this lad in an Everton shirt!
