Maurizio Sarri set a new Premier League record in Sunday’s 0-0 draw against Everton.
By avoiding defeat, Sarri has gone 12 league games unbeaten at the start of his Stamford Bridge tenure, a feat unmatched in 26 years of the competition.
The record takes him clear of former Nottingham Forest boss Frank Clark, whose 11 games during the 1994/95 season had stood for 24 years.
Upon reaching the landmark, Sarri said: ‘I’m very proud. I have to say thank you to the club because they gave me a very good team. I have to say thank you to my players and my staff. But today I would have preferred three points to the record.’
Jose Mourinho and Luiz Felipe Scolari, who each went eight games unbeaten at the start of their Chelsea managerial careers, in 2004 and 2008 respectively, previously shared the Chelsea record.
