Chelsea boss Maurizio Sarri admits he's speaking directly to certain players this week after defeat to Leicester City.

Sarri admits he was disappointed by the 0-1 home defeat.

"Of course, we will prepare a video about the match," said Sarri.

"For every match, we prepare a video after the match. We will prepare individual videos, the individual mistakes.

"I want to speak with the group first of all, then I want to speak with three, four, five players. I don't know how many at the moment.

"Of course we have to do everything just in order to avoid the same problem in the future.

"The [Watford] match is difficult, we know very well. We have to study very well these kinds of opponents."
