Virtuoso displays aren't the point though. The other poster said that Spurs "are far less reliant on any single player to dig us out of a hole". I'm not sure that's the case.
Kane has now scored 5 of their 7 CL goals, excluding last night's own goal. He didn't score in August and they dropped 5 points at home. They couldn't beat Swansea and struggled at the weekend too when he wasn't scoring. The games so far this season show that when he doesn't score, Spurs struggle. That's the bottom line really, and that's the point I was answering.
Also worth considering that Kane's direct replacement at Spurs, Llorente, is a good player but not near the same level as Kane. In comparison, we have Lukaku/Zlatan, City have Aguero/Jesus, even Chelsea's replacement for Morata in Batshuahyi looks like he's developing well. It's more difficult to say with Liverpool as they don't really play with a central striker, and while Arsenal don't have any striker of Kane's level their replacement for Lacazette being Giroud is of a similar level to their main striker.
All of these things point to a reliance on Kane. Not in the same way as they relied on Bale, but to a fairly similar magnitude.
