Thomas Tuchel will be feeling pretty pleased with his start to life at Chelsea after three wins out of four - but he'll be keen to ensure the Blues do a professional job against Barnsley in the FA Cup.
Chelsea travel to Oakwell to face the Championship outfit hoping to book a spot in the quarter-finals, and while the London side will be heavy favourites to progress, Barnsley will be right up for this game and should be eyeing a seismic cupset.
Tuchel is expected to make a handful of changes for this game to keep his squad fit for an important run-in as he bids to make the top four.
