Chelsea are on the right track, but to say that they are improving is not right. the result against Tottenham Hotspurs can be deceiving for their players, it could be a good boost for their mental, but also could trigger complacency in the squad. I think poch knows that they than that to win their next games which are getting harder and harder because other teams pay attention towards Chelsea's progression.
Game against Mancity is the biggest test for Poch and Chelsea as a team to know if have they found their character as a team or just still raw. I think the result will show how far they have become.
Chelsea will suffer if they do not change their game pattern, they should be able to reinforce their styles when it comes to scoring goals. Rating Chelsea performance in previous matches is quite easy but when it comes to elite teams, I believe they do not stand a chance because they're still building, Mauricio Pochettino have a whole lot of work to put in for the team, facing Manchester City on Sunday, that's his main test and not some random average team or winning an elite team that has two red cards. Winning Tottenham Hotspur with two man down doesn't mean they're right back on track, the Blues are yet to prove themselves to the supporters this season.
I think this is not the right moment to talk about the suffering of Chelsea because what are we all here going to say when they beat Manchester City in the next game after they beat Tottenham in the last game?

I know this is utopian, but maybe not entirely. Manchester City isn't the same team as last season in terms of their strength and if Chelsea has a great day, what if they beat that team and get the next 3 points from the title defender? That could be what all Chelsea supporters have been eagerly waiting for.
