Hagi and Morelos are two completely different entities.
Hagi grew up in the shadow of his dad a great footballer, he’ll have had it drilled into him from a young age what it takes to make it as a professional footballer from training to nutrition to attitude.
Morelos grew up poor as fuck in effectively a third world country and made it because of raw talent , probably hadn’t seen a sport scientist or nutritionist until he got his move to Europe,
Morelos is probably more similar to young Scottish players that have came from a scheme eating fucking turkey dinosaurs and trying to shag birds at the weekend compared to Hagi who lived a life or privilege
