Chelsea fans may be missing out on European football this season after a disappointing 2015/16 campaign, but Antonio Conte's squad seem to be enjoying themselves nonetheless.
The Chelsea pair were filmed by the Blues' social media team playing a game of keepy-uppy as they warmed up, with Willian in particular displaying his superb skills with variations of a round-the-world trick to keep the ball in play.
Antonio Conte's Blues trained at the Bridge while the likes of Arsenal and Manchester City prepared for Champions League action, while Mauricio Pochettino's Tottenham host Bayer Leverkusen at Wembley Stadium on Wednesday.

Willian and Oscar's training antics seemed in contrast to Fabio Quagliarella's declaration that Conte is a strict disciplinarian in training.
Quagliarella, now 33 and playing for Sampdoria, won three straight Serie A titles with Conte at Juventus between 2011 and 2014, with the forward revealing that the Italian coach left no stone unturned in his bid to ensure his team were tactically prepared for games.

"With Conte, it was back-breaking both in training and in games," Quagliarella told Mediaset television.
"The intensity was so high, and you could see that also in our games.
"He is phenomenal in the way he prepares you tactically.
"There were a lot of rules to adhere to - if he gave us a day off, we weren't allowed out of Turin.
"He got angry very often - very, very often."
