16 min: Sanchez saves from Castellanos! West Ham come again with Wan-Bissaka and Bowen slips in Castellanos, whose shot is well struck to the near post but stopped by Sanchez. Chelsea are on the ropes a bit.

14 min: West Ham look a real threat. Fernandes finds Summerville on the left of the area and gets it back. The midfielder’s shot is blocked before it can reach Sanchez but it draws grumbles from an otherwise quiet home crowd.

12 min: Wan-Bissaka blocks a Garnacho cross out for a corner near the boisterous away end. Areola punches clear and West Ham break with numbers. Gittens comes across to stop the counter and gets a foul off Summerville.

10 min: Chelsea look to respond as Garnacho fronts up Wan-Bissaka again. This time the winger doesn’t have the confidence to take him on and instead plays it back.

Wan-Bissaka wriggled away from Garnacho down the right and plays it into Bowen on the edge of the area. He cuts inside on to his left and floats a cross that evades Castellanos on its way to the back post, where it deceives Sanchez and finds the side netting.

6 min: Garnacho ducks past his former Manchester United teammate Wan-Bissaka after playing a one-two and wins a corner. Areola flaps at the delivery but it comes to nothing.

Leroy Rosenior, formerly of West Ham, is sitting a couple of rows behind the dugout, where his son is calmly waving around instructions.

4 min: Palmer looks dangerous for Chelsea, digging out a curling cross to the back post that Wan-Bissaka does well to flick away with Garnacho waiting behind him.

2 min: West Ham have the first effort on goal. Pablo dispossesses Caicedo in midfield, feeds it to Castellanos in the penalty area but his shot is very weak indeed and Sanchez scoops it up.

Enzo Fernández and Jarrod Bowen lead the teams out. Anthony Taylor is the man in the middle. We’re ready to go.

Warm-ups are done at the Bridge. Chelsea were harking back to the 90s with their training strip based on that notorious away kit.

“I was pretty stunned to see all the changes for Chelsea,” writes Sue. “Confused - still a good line up but ‘it’s not quite Carling’. Disrespectful towards West Ham? Or just juggling to find his best team?”

To be fair to Liam Rosenior, Chelsea play again on Tuesday in the Carabao Cup against Arsenal. Rest players in that one and you risk real embarrassment. Today is their ninth game this month.

A West Ham season-ticket holder has been banned for five games after the unfurling of a banner that said “Time 2 Sell – Name Your Price” in protest at the club’s board at last weekend’s home win over Sunderland. Joshua Wood, 27, was said to have breached regulations regarding items allowed inside the London Stadium, with the banner adjudged to have been too big. He plans to appeal.

Wood said: “They’ve been clever in how they’ve approached it because they’re not saying I’ve been banned for protesting. They’re saying I’ve been banned for bringing up a banner which doesn’t fit the regulations of their dimension sizes. I have no doubt that if it said: ‘We love you, Brady and Sullivan’ we wouldn’t be talking today.”

Full time in the Premier League 3pm kick-offs

West Ham can close the gap to Leeds to three points.

“Transfer wishful thought … ” writes Chelsea fan WB. “Straight swap Liam Delap for Nicolas Jackson before the window closes? We can all learn from our mistakes, no shame in it.”

Yes, Delap has not really got going since joining from Ipswich last summer. He worked with Liam Rosenior at Hull though, so … maybe it’ll all come together. Faith has been shown in him today, especially after João Pedro’s performance on Wednesday.

Remember you can get in touch with me via email if you have any predictions or thoughts on this clash. If you support Chelsea or West Ham, perhaps you have an opinion on what your club need before the transfer window shuts on Monday.

West Ham have been linked with another of Chelsea’s frozen-out players in Axel Disasi. The defender has played once this season – for the under-21s in the EFL Trophy. Chelsea are still chasing Jérémy Jacquet of Rennes.

Here’s our transfer tracker:

Raheem Sterling is no longer a Chelsea player, as of this week. He hadn’t played for 18 months and had been training alone but the 31-year-old’s lucrative contract has now been terminated.

Jacob Steinberg, who is at Stamford Bridge today, has been wondering what is next for the former England international:

Sterling’s departure is said to represent a sizeable financial saving for Chelsea. His contract, which had 18 months left, has not been paid up in full. It was time for a clean break. Sterling is too young to retire. He is probably done at the highest level but there will be managers who will back themselves to revive him.
