This is actually the worst ever start to a title defence since the Premier League was formed in 1992-93.

Chelsea edge Blackburn on goal difference - it's a full six points to the next worst (David Moyes's Manchester United).

Chelsea legend Ron Harris has been speaking to BBC Radio 5 live's Sportsweek.

"This time last season they had one of the best defensive records in the Premier League. This season they are leaking goals. That is the biggest concern.

"I don’t think Jose has allowed them to be complacent but one or two players are having a poor time.

"They have had one or two poor decisions go against them. It is natural people get irate. Maybe Jose sits down and thinks he could have done things in a different manner but that is the way he is.

"It is only like you driving to work and someone cuts you up. You react.

"Let's be fair, if you look at his record, you don’t become a bad manager in 10 games. I have not seen too many Chelsea supporters moaning and groaning. They are disappointed with results but I am sure Jose will turn it around."

Chelsea defender Gary Cahill told BBC Sport: "[The mood in the dressing room] is not great - like you’d imagine when you lose games. Last season we weren’t used to it. The lads are devastated. 

"You’re left scratching your head sometimes. In the first half the Cesc Fabregas goal could have been given and we had the goal that was nearly over the line. That sums up the way we’re going. 

"And then we’ve got the sending off. Originally we played on – we thought the referee had played on. Maybe the assistant called it back, I’m not sure sure what’s happened there. We’ve not had the rub of the green but we’re not feeling sorry for ourselves. We have to work hard to turn this round.

"Not many words are being said at the moment. I’m sure we’ll reflect in next day or so. We worked really hard at 10 men and had the majority of the play in the second half. It’s a summary of our season at the minute."

No doubt about the big story of the weekend so far.

Chelsea lost again - this time in the derby with West Ham - and even worse Jose Mourinho was sent off for being an angry man.

In fact Mourinho was so wound-up he refused to do an interview afterwards, and didn't send out any coaches in his stead (one of his coaches was also sent off).

It was down to Gary Cahill to face the media alone...

And across Europe there are derbies in Vienna, Prague, Athens, Lisbon, Moscow and Istanbul. 

We will turn our attention to the Wear-Tyne derby (apparently that's a thing because Sunderland are at home) at 11:00 but first a bit of general football chat for you.

Derby day. You've got to love it.

League games where the result stands alone - a big or dramatic win will be remembered for years to come, when league positions have been long forgotten.

There are those who say it's only another three points - but everyone knows that isn't really true.

So get yourself settled in for an intense day of football.
