I wonder how much is down to his repeated ankle injuries?
As Kane doesn’t appear to be as nimble as a couple of seasons ago and taking long range shots must put more strain on the ankles than passing.
Don't think it's the injury .. it's Kane
Kane is a rhythm player, always has been (hence the august curse). He has a lot of attributes (strength, positioning, passing, finishing, etc.) but he's not a natural athlete, he needs to have a ton of consistent game time (also why he was never brilliant on loans). The injuries just stopped him from ever getting back to full match sharpness for some time now.
