Derby County v Chelsea preview
Jose Mourinho plans to field a strong team when Chelsea play at in-form Derby on Sunday in the FA Cup third round.
Defender David Luiz is available after being suspended for the Premier League win at Southampton and could return.
Midfielder Frank Lampard (muscular injury) and right-back Branislav Ivanovic (knee) are out until the end of the month, while Marco van Ginkel (knee) is continuing his rehabilitation.
Mourinho might decide to give some of his fringe players a chance to impress after a busy run of games over the festive period.
Derby will be without striker Johnny Russell after he suffered a fractured cheekbone in the New Year's Day defeat to Wigan.
Steve McClaren is sweating over the fitness of key midfielder Craig Bryson after he picked up a calf injury against Wigan.
Jeff Hendrick could replace Bryson in midfield if the Scottish ace misses out having recovered a bout of concussion.
