Actually I am not surprised by Chelsea's improved performance, I think they should be like that after their big investment in players and coaches. Chelsea has brought in so many players and changed several coaches to support the team's performance to be better and more competitive, so basically this is the result of what they have invested.
Seriously, Chelsea’s current performance is surprising to me. Chelsea spent so much money last season, and their performance was poor, so because they spent so much doesn’t mean they will have to perform well, and since they are having a new coach, I was thinking it’s going to take some time for the coach to get used to the players, so I wasn’t expecting him to fix Chelsea's problem within a short period of time, but as we can see, Chelsea is performing well, they are currently in second position, Liverpool which is in first position, is ahead of them with just three points, and from the way Chelsea is playing currently, I am always having confidence in them to win most of their matches.
