Sarri made an encouraging start to his tenure as Chelsea were unbeaten after their first 12 top-flight matches under him but the Blues have faded out of title contention and face a battle to finish in the top four.
Chelsea suffered their worst defeat in almost 28 years as they were hammered 6-0 by Manchester City yesterday, just two weeks after losing 4-0 at Bournemouth.
The Italian is at a loss to explain what has gone wrong, but is determined to get to the bottom of the situation. If he is given the chance that is.
"I didn't see my football (against City)," Sarri said after the game.
"At the beginning (of the season) it worked. So now we need only to understand the reasons why at the moment it isn't working. We need to understand the reasons.
"It is not easy. At the beginning, we played better away than at home. Now we are playing better at home than away.
"Something is changing. At the moment I am not able to see the reason but I have to work for this because my target is to play my football, not to change another football because at the moment we are playing another football."
