It's easy for Chelsea to play a team in other leagues than teams in EPL. I thought that Chelsea will start this season in a grand style and win three consecutive matches but they failed to win their first match. From the look at their performance yesterday, Maresca needs to work more on the team to stable their performance. Let it not be that they will be very strong in one match and become weak in three to four matches.
Premier league will always bring out your actual essence and strength as a player, coach or team. The competition in Premier league, the attention and even the fan base is one which put some level of pressure on everyone to be at their best such that striving in the premier league will be for the well deserved and not the average, Chelsea is to me still in their recovery/build up phase, so we can only follow them as they perform and drop every expectations.
