Jose Mourinho has taken pains to point out that Chelsea aren't yet 100 percent sharp despite our flying start to the season. And that, perhaps, has something to do with the fitness and form of the players who played late into the tournament at Brazil 2014. Chelsea have three members of the Brazil squad that reached the semifinals and imploded as well as André Schürrle, who had a happier (but just as lengthy) campaign with Germany.
None of them has reached their absolute peak yet, and for the manager that will take time:
Not one of them is in super form, like [Cesc] Fabregas, [Nemanja] Matic, [Branislav] Ivanovic. At this moment, they're not. It has to be step by step. In this last part of the World Cup, we had players in the same position: Ramires, Willian, Oscar and [Andre] Schurrle. I couldn't say 'you four, holidays, I can do without you,' because I couldn't do without them.
Look at Schurrle. He really wanted to make an impact against Bolton [in the Capital One Cup on Wednesday], and his performance was really good. It was important for him to play 90 minutes. He was one of the guys, like the Brazilians, who reached the last stage of the World Cup, his holiday was very short. It will take time for him
Chelsea are already playing very well despite obvious weaknesses and a lack of fitness in some key players, so I'm looking forward to seeing how everything shakes out once the structural issues has been addressed and everyone's at full health. This season could end up looking pretty special.
