With the ex-Napoli manager at the helm, the Blues have embarked on a 16-match unbeaten run in all competitions, seeing them sit second in the Premier League standings while also looking on course to qualify for the knockout stages of the Europa League.
Chelsea head coach Maurizio Sarri was relieved to advance in the Europa League after enduring a disappointing performance from his team while battling a fever in Belarus. Neither did poorliness stop the Italian from becoming visibly angry on the touchline as his players appeared to lack the appetite to impose themselves.
'Today I was in trouble, too, ' Sarri said afterwards.
Sarri also confirmed that Alvaro Morata has remained back in London to train rather than play another match.
'But I know very well that strikers want to score.
Sarri remarked afterwards: "I think we didn't play very well, I didn't like the first half because we moved the ball only horizontally and slowly, so it was hard to be risky".
'We felt that for him it's better to play, not for 90 minutes, but to play after two weeks of not playing. The best thing about this evening was the result.
'But I don't want him to be anxious about scoring because, for us, he's very important and very useful. I think it is better for him to stay fit with two or three trainings than only with matches.
"He [Morata] played for three matches in a row, so I thought it was better to rest at Cobham and have good training", Sarri said. "You always have to work hard and keep the faith". 'He's a very important player for us because he's very useful for the team. "Then we managed not really very well the last 15 minutes".
'And so for his confidence I think it's very important.
