Antonio Conte believes Chelsea must improve following their 3-0 loss to Arsenal, to avoid finishing in the middle of the table.
The blues finished 10th on the log last season after a disappointing start, with Conte hired to right the ship.
Nevertheless, the former Italy boss has admitted they still have plenty of work to do.
“We must improve a lot of if we want to stay up [at the top] and not in the middle of the table,” said the Italian.
“But my message is not important. The most important message is the one that arrives on the pitch. We must all understand this message, and find very soon the right solution to improve.
“I don’t sleep [after a loss like against Arsenal], I don’t sleep for two nights. When I don’t sleep, I reflect. And it’s important to reflect.
“I got angry at half-time but I prefer to keep my words. There are rules in the dressing room. Sure I was angry but my players were also angry. We were not satisfied with our game, with our performance.
“I have to find the solution very, very soon because against Arsenal we played a very bad game.”
The reverse at Emirates Stadium made it three winless top-flight matches for Chelsea, who sit eighth.
