Graham Potter's first weeks in charge of Chelsea have been eventful and his handling of key players in upcoming matches will be an early test of his man-management skills.
The former Brighton boss was without both N'Golo Kante and Edouard Mendy for Chelsea's match against RB Salzburg - Potter's first and so far only game in charge - whilst the pair nursed knocks that were picked up under Thomas Tuchel.
Kante has only played two matches this season after injuring his hamstring in the second half against Tottenham and Mendy missed the first Champions League group stage game with a knee injury which subsequently ruled him out of the next game too after the scheduled game against Fulham was cancelled.
