Thomas Tuchel says the statistics highlight the 'aura' that Mason Mount brings to the Chelsea team, saying the midfielder comes close to undroppable when fully fit.
With Mount in the starting line up, Chelsea's win percentage is 89 per cent this season. Without him, that reduces to 46 per cent. Tuchel said on Friday that he and his analysts study these stats after taking the lead from basketball.
Mount is expected to start against West Ham on Saturday, with Reece James, Timo Wener and Jorginho all fit to feature after playing no part in Wednesday's win over Watford.
