It reminds me of the early debate between Arsenal fans to know who was the more talented between Reiss Nelson and Saka. Saka isn't flashy, he won't instantly grab your attention, but he's the most consistent young player I have seen. On his worst day he'll give you a 6/10 performance. His decision making was very good until this season (right now he seems too focused on end-product). He's starting to add goals now, and if he can combine his early decision making quality and his new found scoring ability, he'll be up there with the best.
Foden is the most gifted player, and I don't really think it should be a debate. But I'm ready to bet that Saka will reach the top too.
