Chelsea are still in evolution, I don't think the squad is strong enough to win the league if I'm being honest. I don't get why we're under unnecessary pressure. Just because we have a striker and a midfielder doesn't mean we'll be doing great from day one. Chelsea need a game plan capable of breaking down smaller teams and tbh Mourinho has had this problem all throughout his career besides at Madrid, even then when a team parked the bus Madrid almost always ran out of ideas(see United game and dortmund at the bernabeu) and rely on fluke goals and inspiration.
This is why Chelsea aren't winning the league next season, we need 3 more signings.
