Unlucky? You have to work to have luck. He is fat and has 6 goals in 66 matches because of luck? His problem is the lack of professionalism mainly. On top of that, he is one of the most overrated players ever.
Lol no you dont
Casillas made a career of having good reflex and minimal effort in training and was just fine
It's good when you do work and do have luck but it's far from necessary
Isn't that overrated, everyone seen him disappear in CL for Chelsea and get fat several times in summer. Which didn't really stop him putting in great seasons
Nor has he been fat for like 2 years now
That summer when arrived was definitely overweight because he got the dream transfer to a dream team and to work under a dream coach he idolised as a player growing up and after winning his first European trophy. If not sympathetic to that, fine, but he's been OK physically from even November 2019 before he got shinned by Meunier that killed his career and misdiagnoses of microfracture treatment, reinjury, then the metal plate inserted to stabilise growth which ended up bothering him for some time. Some of the photos of him from the time when pandemic first kicked off in May 2020 and he returned to training showed him in fantastic shape.
Output is not a simple function of his effort alone like you want to present it
