While a couple of Chelsea players are out causing chaos around the world, namely Marc Cucurella and Enzo Fernandez, those not on international duty are working hard at Cobham.

The Blues have a huge FA Cup quarter-final tie with Port Vale on the horizon. The League One strugglers come to Stamford Bridge on Saturday evening, looking to cause an enormous upset. As for Chelsea, this weekend presents a massive chance to book a date at Wembley.

Over the last week (or so), those players not chosen by their countries for the ongoing international break have been working closely behind the scenes with Liam Rosenior and his staff. So, with that being said, football.london takes a look at a couple of things we spotted in the latest batch of training pictures released by the club.

Levi Colwill was once again pictured in training with his Chelsea teammates as he nears his return from an anterior cruciate ligament (ACL) injury he suffered back in August. The England international has not kicked a ball competitively this season, with hopes that he will before the campaign concludes.

Colwill has been training, in some part, with his colleagues over the last month at Cobham but Rosenior has refused to put a timeframe on when we will see the academy graduate back in action. More positive signs, though, that Colwill is working with the rest of the squad earlier today.

Alongside Colwill, football.london could make out another 10 Chelsea players spotted in training. Liam Delap, of course, who will be hoping to prove a couple wrong on Saturday if he gets the chance against Port Vale in the FA Cup.

Alejandro Garnacho was once again left out of the Argentina squad, so he was among those training in Surrey. Estevao Willian was not called up by Brazil as he returns to full fitness, with Romeo Lavia in a similar situation with Belgium.

Wesley Fofana, Tosin Adarabioyo and Benoit Badiashile all took part in Monday's session. Dario Essugo, too, having recently returned from a long-term injury, while Robert Sanchez and Marc Guiu were also taking part in Cobham.

There is set to be a host of players returning to the training ground on Thursday, including the likes of Cole Palmer, Cucurella, Jorrel Hato and more. However, the likes of Fernandez, Pedro Neto, Joao Pedro and Andrey Santos could return on Friday given the amount of travel they have to do.
