Chelsea boss Maurizio Sarri has played down their title chances after a 100 per cent start to the season.

Sarri oversaw Chelsea's 3-2 win over Arsenal yesterday.

He said: “We are not title challengers, not in this moment.

“We have to improve in the defensive phase and I'm not talking about only the defenders.

"We did very well for 75 minutes — 15 minutes at the end of the first half was horrible."
