The District Line is closed west of Embankment Station and on the whole of the Edgware Road branch, including the line down to Wimbledon.
This means for the match at Stamford Bridge, Fulham Broadway Station is closed all day and there are no District Line trains running to any nearby stations on that branch of the tube network.
The Circle Line is also affected and is closed between Edgware Road and Aldgate (via Victoria).
The Mildmay Line is affected too from 7.30pm on Saturday, with no service between Shepherd's Bush and Willesden Junction. There will also be a reduced service between Shepherd's Bush and Clapham Junction.
