Chelsea coach Thomas Tuchel is confident his team will be able to get rid of their problems quickly if the players pay more attention to details after the 3-2 defeat at West Ham United at the weekend, dropping from first to third in the English Premier League.
Tuchel told the club's website: "There is no need to question or create confusion about the whole picture of the team. From my point of view, it is all about the details, and for this I am confident that the team will be able to solve its problems quickly."
"No one wants to make mistakes, but we won't benefit from just saying let's not make mistakes anymore," he continued. We have to improve in terms of making the right decisions at crucial times, and also in getting a clean sheet or conceding only one goal at the latest.
The German coach admitted that he made a mistake by sending Bromelo Lukaku as a substitute at half-time instead of the injured Kai Havertz, as the Belgian striker lacked the sensitivity of matches.
Lukaku has not played for more than a month after missing with an ankle injury and making a short appearance against Manchester United and Watford.
Tuchel added: I made a mistake. I do not think that he is physically ready to play 45 minutes, but we pushed him after losing the efforts of Haveritz, the latter played a big role in the defensive side and also in the set-pieces, which were a great danger from West Ham.
Chelsea will meet Russia's Zenit St Petersburg in their last Champions League group stage match on Wednesday.
Chelsea qualified for the knockout stage, but they are level with 12 points with Juventus at the top of Group H.
