What to look out for at Chelsea this week, with another Premier League London derby and a UEFA Women's Champions League play-off decider to come.
Tuesday
Chelsea Women are travelling to Spain for the second leg of our UEFA Women's Champions League qualifier against Real Sociedad. Fans have already had the chance to watch them train at Cobham this morning, live on the Chelsea Official App and website, before Sonia Bompastor and her players departed for Spain.
We will confirm the travelling squad from 6pm and will also bring you any team news as we hear it from Sonia Bompastor.
In the men's game, Tuesday is transfer deadline day, with the window closing at 11pm UK time.
We have already seen Chelsea sign a new defender in Honest Anahor and parted ways with striker Marc Guiu, who has joined RB Leipzig on a permanent transfer.
You can find all the Chelsea ins and outs here, and we will bring you the latest news throughout the day and night first, as soon as they are made official, right here on the Chelsea Official App and website.
Wednesday
We will be wrapping up all the activity from another big transfer window for Chelsea on Wednesday morning, when Xabi Alonso's squad for this season will be officially finalised.
We should also hear from Chelsea defender Jorrel Hato following his great start to the 2026/27 campaign.
Chelsea Women take on Real Sociedad looking to finish the job and book our place in the league phase of this season's Women's Champions League, with a 5-2 lead to defend in Spain from last week's first leg at Plough Lane.
The game kicks off at 6pm at the Estadio Izan and it will be streamed live for free in our Real Sociedad vs Chelsea Women Match Centre on the Chelsea Official App and website.
Before that, the youngsters will be in action, when Chelsea Women Under-18s travel away to Southampton in the PGA Under-21 Women's League for a 2pm kick-off.
Thursday
Match highlights and the full 90 minutes (or longer if it goes to extra time) of Chelsea Women's Wednesday-night Champions League qualifier against Real Sociedad will be available to watch from first thing on Thursday morning.
We will also be bringing you all the reaction from Bompastor and her players to what will hopefully be another successful evening with a place in the league phase secured.
On the men's side, we will start to look ahead to the big London derby with Arsenal.
Friday
Xabi Alonso will be sitting down at Cobham to speak to the gathered media in his pre-match press conference to preview our trip to Arsenal. You can watch it live on the Chelsea Official App and website, or catch up on demand later in the day.
Chelsea Women are switching their focus from Europe back to domestic matters for the weekend, starting with Bompastor's pre-match press conference to preview our Women's Super League meeting with Aston Villa. That will take place at Cobham at 3pm on Friday and you can watch it live on the Chelsea Official App and website, or catch up on demand afterwards.
Saturday
Chelsea Women's first match at Stamford Bridge since it became the permanent home of all our WSL fixtures arrives on Saturday, when the Blues host Aston Villa in our opening league game of the season.
