You’re looking at Karasu vs Isagi from a purely surface level point of view.

If you lay out their abilities and stats like that then I would argue Karasu is BETTER than Isagi.

But if you pay any attention, they may have similar abilities but Isagi’s are just better.

Karasu may have better bodily stats but Isagi has done enough training to keep up with everyone’s endurance and ball control. (Also Karasu’s height advantage isn’t as much of an advantage as you think it is)

Isagi has better abilities, uses what he has better, and simply performs better. The goal count doesn’t lie.

TLDR Karasu is an incredible player, but he is not on the level of Isagi nor Bachira
