The Blues are aiming to win the trophy this season after having been beaten by Arsenal in the final at Wembley back in May of last year.
It has been a largely disappointing season for Chelsea FC under Antonio Conte, with the Blues having struggled to maintain a title challenge after having won the Premier League last term.
The Blues ended up in fifth place in the Premier League table last weekend as they missed out on a place in the Champions League for next season.
Hazard and Willian will both be hoping to start up front for Chelsea FC as the Blues look to try and beat Manchester United to the last remaining domestic trophy on offer this season.
And the attacking duo looked to be having fun as Chelsea FC continued their preparations for the game at their Cobham training base.
Chelsea FC are bound to be linked with a host of players in the coming weeks and months as they look to assemble a team capable of winning the Premier League title next season.
