Chelsea head to Oakwell on Thursday evening for an FA Cup last-16 tie against Championship side Barnsley.
The in-form Blues are unbeaten in five games in all competitions, winning four of those, while Barnsley have gone three games without defeat.
Thomas Tuchel's men were made to work hard for their 2-1 victory at Sheffield United on Monday and the German coach may elect to make some changes for this match.
Here, Sports Mole looks at how Chelsea could line up against Barnsley.
Out: Thiago Silva (hamstring)
Doubtful: Timo Werner (leg), Kai Havertz (knock), Christian Pulisic (personal reasons)

Chelsea boast plenty of squad depth and that could be put to good use on Thursday assuming Tuchel rotates.
Billy Gilmour, strongly linked with a loan exit in January, will be hoping to start for the third FA Cup game running, while Kepa Arrizabalaga is another who has been made to settle for cup appearances.
Tuchel has used a back five since replacing Frank Lampard, but a back four could be the formation of choice at Oakwell, with Ben Chilwell and Reece James expected to get the nod at full-back.
Thiago Silva will definitely play no part because of a hamstring injury, though Christian Pulisic and Kai Havertz are likely to be back in contention.
Tammy Abraham scored a hat-trick against Luton Town in the last round and has now been directly involved in eight goals in his last six FA Cup starts (five goals, three assists), so he will be confident of getting the nod over Olivier Giroud and fitness doubt Timo Werner.
