I wouldn't concern myself with who's at the top of the table at such an early stage of the season...
Of course, in terms of winning the league, but for the smaller teams, like Aston Villa for example, if they win today, that'll be five wins (100% record), with a game in hand, and it already makes it kinda impossible for them to be relegated at the end of the season, except they experience a really terrible capitulation; as five wins is already more than half of the games they won in the entire last season (9 IIRC).
I really dislike Chelsea so I hope they change 15 managers in the next 3 seasons.
Lol, that's not beyond Roman Abramovich, Lampard should be given more time imo, even if he does not deliver anything this season, jurgen Klopp was given quite a while at anfield, before he was able to land the big trophies for Liverpool.
