Willian, who scored a magisterial freekick against the Ukrainian side on Thursday, believes crunch time has now come at Stamford Bridge and the potentially season-defining stretch must drive the west Londoners to go for broke in every fixture they come into.
"Jorginho, if the other players don't move without the ball, is in trouble", Sarri told his pre-match press conference.
This club is still young and we need people like him to improve the quality in terms of Champions League trophies in the room, he can help us.
'He is able to dribble past five, six or seven opponents, of course he is a great player - he can resolve the situation in every moment.
David Luiz has emphasised Chelsea's belief in Maurizio Sarri's philosophy, saying a top-four finish and Europa League title would mark a successful season.
The Blues head in to the game tomorrow sitting sixth in the Premier League table but they are just six points adrift of third-placed Tottenham with two games in hand so the race for Champions League qualification is extremely tight.
"I think that we made a lot of mistakes, but we deserved to win", the Italian added.
"We were unlucky because we conceded a goal in the first situation inside our box - the first and the last in all the 90 minutes".
"For many years, [people] were not happy because Chelsea were winning without playing very good football and now Chelsea is playing very good football and sometimes we don't win so people are not happy". It wasn't easy as the problem wasn't the system, but the way that we were playing. The team could defend in the last 20 metres with 11 players.
Asked why he chose to switch his tactics, Sarri replied: "Because, for the first time, we were playing against a team who didn't want to play".
The Blues had over three quarters of possession but despite their time on the ball, just one opportunity was created for Gonzalo Higuain after 20 minutes. We need to move the ball faster. It is hard to score playing with four or five touches.
