The Blues have sprung a huge surprise in the cup and rested two of their most important attacking players against their London rivals
Chelsea have left Diego Costa and Eden Hazard on the bench for their FA Cup semi-final against Tottenham - with Michy Batshuayi earning his first start since January for the club.
Willian will also step into the forward line to replace Hazard as Chelsea appear to rest players with a Premier League game against Southampton on Tuesday.
Nathan Ake starts in place of Gary Cahill, who is out with a virus that saw him hospitalised in the midde of the week.
