Chelsea manager Jose Mourinho is likely to rotate his squad for Sunday afternoon’s trip to Derby County in the third round of the FA Cup.
The Blues impressed in the league over the Christmas period, taking ten points from the twelve available after beating Southampton, Liverpool, Swansea City and drawing 0-0 with leaders Arsenal.
Frank Lampard and Branislav Ivanovic have both been ruled out for a month, and join Ryan Bertrand and Marco van Ginkel on the side-lines.
Manchester City beat Chelsea 2-1 in the semi-finals of the competition last April to condemn the club to their first FA Cup defeat, within 90 minutes, since they lost to Barnsley in March 2008.
Derby currently sit in fourth place in the Championship, and lost for the first time in ten games last time as Wigan Athletic ran out 1-0 winners when the sides met at the iPro Stadium on New Year’s Day.
They are the top scorers in the second tier with 48 goals in 24 matches, though they have also conceded the most, 30, of all the sides in the top fourteen of the division.
Chelsea ran out 6-1 winners the last time the sides faced each other, in Derby’s disastrous Premier League campaign of 2007/08.
