You are right, the arrival of new players certainly brings new hope to the club. But they may need time to adapt to the team's style of play and strategy.
Chelsea's performance wasn’t really good in their last match, but I am sure there will be some improvement in Chelsea this season. This is just the beginning of the season, and it won’t really be easy for the new players joining the club, but with time they will be able to adapt. From the way Chelsea is playing this season, there are really great changes in their performance, but they are still having some lapses, which I am sure their coach will be able to figure out with time. I'm sure Chelsea is going to end the season in a better position.
I just hope it won't take them long to be in the best form to perform better, the beginning of the season is the best time to accumulate some points to stand a better ground to be in a better position. Chelsea just need to adapt this winning mentality in them , it will really change a lot for them that will increase the level of their performance. The last game Chelsea played against West ham the result was so disappointing, I wasn't expecting the huge score from West ham that it will be so easy for them to defeat Chelsea with a fine score.
