One team I'm concerned about is Tottenham. I don't see much improvement from their last season's performance.
Chelsea played good and so did Brighton. Werner, Mount had a good game. I was expecting a bit more strong debut from Kai Havertz but didn't went as expected - maybe coz of playing in a different position? Or sudden change of play style? Anyway it's just starting and shows he has still to work on. He will improve at point.
Kepa yesterday should have made that save. It wasn't that hard shot to pull off a save. I won't be shocked if Lampard picks Willy Caballero in next match. Right now, Edouard Mendy is also reported to have completed his medical at Chelsea and would be soon announced officially (https://www.express.co.uk/sport/football/1335463/Chelsea-news-Edouard-Mendy-Stamford-Bridge-transfer-confirmed-announcement) . Now I wonder where the future of the most expensive goalkeeper - Kepa is at?
