A wonderful return by Kevin De Bruyne to the Premier League! 
He did amazing things in the Newcastle match despite being subbed in in the second half. He is always ready for duty to perform strongly. It looks like the injury lasted quite long didn't affect his skills in a bad way at all. He is 32 years old by the way but still plays like he is in his much younger time periods.
Haaland is also soon joining the team. With having Haaland and De Bruyne at the same time Manchester City will be much more competitive for the PL title. Salah had better return quickly to Liverpool.

When talking about Manchester City you mentioned Kevin De Bruyne and Haaland, but when talking about Liverpool you only mentioned Salah. I think that's the biggest difference between the two teams. Manchester City have more players who can influence the outcome of the game. Liverpool are weaker than Manchester City in this regard. I think that will be the deciding factor for the title. When Kevin De Bruyne and Haaland start to contribute, no team will be able to stop Manchester City.
