Chelsea boss Jose Mourinho is already in his seat, and the teams are in the tunnel at Upton Park... here they come.

Clive Allen
BBC Radio 5 live at Upton Park

"It normally takes players a while to adjust to the Premier League, especially being introduced from abroad when they come from so-called lesser leagues. But West Ham's Manuel Lanzini appears to be right at home based on what we've seen so far."

"Don't put wings on me, I am no angel."

Chelsea's Diego Costa, 27, has been criticised for his aggressive approach but says he has achieved so much because of the way he plays and will not "change because of other people's opinions".

The Brazil-born Spain international striker told Football Focus every player changes during competitive games, doing "everything to win" for their team. Watch above.

After 92 years, this is the final east vs west derby between these teams at Upton Park (in the league anyway).

'London Calling' is blasting out of the tannoys pre-kick-off to help to get the fans in the mood but will they also get a memorable game to mark the occasion?

West Ham make one change from the team that beat Crystal Palace last week - on-loan forward Victor Moses is ineligible to face his former club and is replaced by Mauro Zarate. Andy Carroll is on the bench, so the striker's wait for a first league start of the season continues.

Starting XI: Adrian, Jenkinson, Tomkins, Collins, Cresswell, Noble, Kouyate, Zarate, Payet, Lanzini, Sakho 

Subs: Randolph, Carroll, Valencia, Obiang, Ogbonna, Jelavic, Antonio

Speaking of predictions, here's Lawro with his thoughts on what will happen at Upton Park.

"Chelsea beat Aston Villa last week, albeit without playing particularly well, and I see a similar outcome this time after what could be a horrible, scrappy game," he says.

"I don't think West Ham will get much joy out of trying to hit Chelsea on the break."

Lawro's score: 0-1

The Hammers have already upset Arsenal, Manchester City and Liverpool this season so their manager Slaven Bilic's ability to beat the big boys is well documented.

Before we get carried away, it is worth pointing out that all of those wins came away from Upton Park, though, and West Ham have actually only won one out of four home league games this season. Chelsea might be short of form, but adding them to that impressive list of scalps above will not be easy.

Yes, while West Ham are unbeaten in six games and riding high in fourth place in the table, Chelsea are languishing in 12th.

It is late October, which seems ludicrously late for the defending champions to still be trying to secure back-to-back league wins for the first time this season. 

That's one of the prizes on offer for Jose Mourinho and his not-so-merry men this afternoon, though.

Hello. There are three derbies in the Premier League this weekend - Manchester, Wear-Tyne... and east vs west London. If you are reading this, then I'm sure you will realise how much this match matters to both sets of fans.

They say form goes out of the window in these games - but if that is true, then Chelsea are the favourites, surely?
