Maybe he will be. But I don’t think your second statement is true in football anymore. Teams do spend megamoney on players that haven’t done it consistently now. Ekitike, Sesko & Woltemade are all examples of that. Or maybe it’s just a case that £60-70m isn’t considered “mega-money” by top clubs anymore. Either way, that’s the going rate for top Premier League clubs buying highly rated young players nowadays.
Semenyo’s only really hit form the last season and a half and he’s going for 65. Wharton and Anderson will go for around 100m and they’re not exactly veterans with 150 PL games under their belt.
