Not winning a cup isn't on his shoulders alone. That part I agree with.
Is he our leader on the pitch right now ?
We can all hope he reaches peak performance for the sake of the team, but right now, he is way off. He hasn't been the same since the farcical golfing interview with that maggot.
He is a shadow of prime Kane. I say this as a fan of Harry's.
In my humble opinion if you're looking for on-field leadership, inspiration, call it want you will, you look to Son.
Maybe Harry has a greater ceiling, but the gap between Son's best and worst performances are less obvious than those of Kane.
