I don't know if he should or shouldn't have won PotS - it's hard to separate the individual's season from the context of the team as a whole. I don't think it matters tbh.
But imo Saka is the best pure attacker in the League on ability alone. Just about every facet of his game is not just good, it's fantastic. KDB for me is one of the smartest players in the League atm, but not when compared to similar players of the recent past - I think he just has absolutely extraordinary ball-striking technique. That's his superstar quality, not his intelligence. For example, I'd say Ødegaard has much better awareness and intelligence.
But I was talking more about pure attackers when I mentioned Saka. Someone like Bernado Silva is similarly intelligent and aware, but he's not a pure attacker who has to also be the tip of the spear in the way Saka is.
The kid is absolutely extraordinary!
