- Chelsea are undefeated in their opening 11 Premier League matches of this season (W8 D3 L0) - they won the league in the previous two seasons they achieved this (2005-2006 and 2014-2015). Any fears that Chelsea would struggle to import Sarri's style of football from Naples appear to have been unfounded: 15 games in, they are still unbeaten. Our live coverage lets you follow all the key moments as they happen.

'I can score hat-trick [so it] is not flawless day but we take three points, we are in first three places. I can say to the club my opinion about what I think I need but my job is to try to improve my players. We are trying. I don't know how many points we can cover in the near future but first of all, we try to cover the gap and then we can try to think something different.
"For now, I have to send to my players the message that only this match is important". More often than not he is double-marked, with any opposition team safe in the knowledge they do not have much else to worry about.
