It’s been another busy week for Liam Rosenior’s Blues. Victory at Crystal Palace in the Premier League was followed up with progression to the knockout stages of the Champions League, by beating Napoli in southern Italy.

There’s been no let-off, with Rosenior and his staff putting his players through their paces at Cobham ahead of the Hammers’ visit to Stamford Bridge, and we’ve picked our 12 favourite images from the session.

Friday was split into gym work and then being out on the grass, with Rosenior confirming at his pre-match press conference that Cole Palmer is fit to start against Nuno Espirito Santo’s side.

He was out on the grass, as were the likes of Marc Cucurella, Alejandro Garnacho and Enzo Fernandez.

Defenders Malo Gusto and Benoit Badiashile were pictured in the gym, while Pedro Neto and Liam Delap were among the Blues taking part in some finishing drills with goalkeeper Robert Sanchez.
