They must watch the new Chelsea step when won't to lost trophy for this session.
I believe it's too early to call them City's strongest considering their match fixtures are also against bottom-half or even second-tier club. Yeah, they won big against Barrow but they also lost against Servette, drawn against Palace, and so on. CMIIW. It's nice to see that the top 6 are competitive so far, although it's funnier if so many clubs get freak results now and then.
Topping the table with just 1pt is not a comfortable one not when you have teams like Manchester City and Arsenal occupying 2nd and 3rd position respectively, for now the league has just begun.
To be fair City won the league 2 times with a point difference iirc. CMIIW. The referee's performance needs to get better though since their inconsistency usually kills games.
