A significant win for Chelsea. It not only gives them 3 points but also reduces the burden on their coach. Enzo Maresca still has a lot to prove because the season has only just started but at least with their first win it can make Chelsea more confident. Chelsea has had poor performances in the last few seasons, so it's very reasonable if their board and fans have quite high expectations this season, so Maresca really has a big burden to bear.
This was indeed a key win for Chelsea as they had lost to City in the previous game and if they had not taken 3 points in the game with Wolves, they would have fallen far behind their main competitors and weakened their position in the fight for the top 4. It can be assumed that most teams will lose 3-2 points in games with City, so if we take this factor into account, we can say that Chelsea are now back in business and can claim the highest places.
