Number Four: Santiago Tomás CastroAge: 21AdvertisementAdvertisement AdvertisementPosition: StrikerShades of: Lautaro Martinez, Julián Álvarez, Carlos Tevez with less wide playWho Is He? Santiago Castro (who likes to go by Santi) was born in San Martín, Buenos Aires, Argentina, nearly 22 years ago. After a decade in that youth system, Castro was given the chance to debut for their senior side in August 2021 at the age of sixteen. Let's be honest, if he had had a 20+ goal season with Bologna, Roma couldn't even sniff his socks in this current market. €35 million for Santiago Castro now is a bet that, at 24, he'll be much closer to Martinez than not.
