I was watching MOTD today and after the Spurs match they criticised Janssen for not getting into a strikers position but working all over the pitch. That is the point. Pochettino's players work for each other (work for the team), not just playing certain rolls. It doesn't matter who scores, so long as somebody scores. That way you have difficulties marking the "striker". Mark the striker and somebody else will score. Yes, we want Kane or Janssen to score; but what is more important is that somebody scored and we get three points. Janssen helped with the goals. End of.
Just a matter of interest; it was 51 years before we had such a good start, as we did on Saturday. We have the best defence in the league, conceding 3 goals (so-far). Everton have conceded 4 and City 5. Four clubs have a better scoring record than us.
