While the article makes an interesting point, it's a bloody obvious one. You could also apply the same analysis to a lot of teams, doesn't mean it is a bad thing.
The way I read it, it was almost dismissive of Silva's tactics (not saying they're not open to criticism) and us be wholly reliant on Gueye. Somehow completely ignoring that Silva is using his resources to maximise output, as a manager should. In my opinion if we were to lose Gueye for whatever reason we would adjust the way we play. We're not as rigid as we were under previous managers (particularly Martinez).
However that was purely my interpretation and others could have formed a completely different opinion of the article.
