Manchester City are the only team with 9 points in 3 games now. They have made a really solid start to the season and Haaland also continues as always. He missed a penalty against Sheffield United maybe but this was still not a hindrance for him to score a goal in the same game. A Manchester City supporter entered the pitch to celebrate the goal with him as well which was an interesting moment.

As usual they are again the biggest title contender for the Premier League. I'm just wondering whether we would see a different team in top 4 again. Newcastle were an example for that in the previous season. They have had an unlucky fixture so far by the way. They got losses against Manchester City and Liverpool consecutively.
Newcastle is having a bit of a hard time and I think this loss against a Liverpool team that was only with 10 men for so long could really tear them down quite a bit. Tottenham is interesting because it was expected that they are much worse off without Harry Kane, but so far they did a goob job in not letting that have a negative impact on them.
But I would still say that Manchester City is far away from their best and De Bruyne is missing badly. But they have been more efficient than the others and that earns them the lead for now.
I agree with your opinion on Tottenham's situation absolutely. They are really doing much better than the expected for now. Honestly they weren't able to become successful in Kane's presence. He was showing an amazing performance but still they weren't able to win any titles. They even finished the previous season at the 8th position despite Kane's scoring 30 goals.
Therefore I thought that nothing would change even if they send Kane from the team this summer. For now they are even doing better but it isn't related to Kane of course. The team effort seems better which should have been like this a long time ago.
