Derby go into this game with a chance to forget about the pressure of playing in the Championship.
The Rams have seen their lead in the second tier of English football slide, with the side now placed third behind Bournemouth at the top of the table and Middlesbrough in second.
Derby reached this stage of the competition with an emphatic 5-1 win in the last round against fellow Championship side Fulham.
For Chelsea, Jose Mourinho will be happy with the way his team have fought through the competition so far.
The League Cup is a competition they are taking seriously though it’s going to be lower profile for the Blues because of their battles in the Premier League, the Champions League and the FA Cup in the New Year.
