The fact about Chelsea is that everyone is expecting them to perform well in the upcoming season because of their performance in the Club World Cup final. If they can maintain their mentality and perform as well as they did at the end of the Club World Cup, I don't think they will face any difficulties next season. Chelsea's Premier League performances were extremely poor, and since they won the Club World Cup, that is why all Chelsea fans are having hope about their performance in the upcoming season.
Chelsea has gradually transformed from the weak form they once had few seasons back and so the improvement is very impressive and that has increased the expectation of people on them as they are even producing results which is making this expectations rise but in the midst of all of this it is better to drop your expectations so that you do not get disappointed if they do not perform the way it had been expected of them. Chelsea will definitely want to make some very brilliant performance so as to see chances to win a trophy again this season.
