Maurizio Sarri equalled a 24-year record when he oversaw Chelsea's 3-1 win over Crystal Palace last weekend.
The Italian has matched former Nottingham Forest boss Frank Clark in going the first 11 Premier League games unbeaten.
While the humble 59-year-old isn't one for individual accolades, that's a seriously impressive achievement.
The Blues currently sit just two points off the top of the table and have scored more goals than any other top-flight side, apart from pace-setters Manchester City.
Sarri has managed that without making wholesale changes. Kepa, Jorginho, and Mateo Kovacic were the only really high-profile signings, so this is largely the same team that finished fifth in 2017/18, an embarrassing 30 points off the summit.
Even the likes of Ross Barkley and Alvaro Morata are hitting form, with the latter now having scored three in his last two league games and only narrowly spurning the chance of a hat-trick against Palace.
The Spaniard will be rested for the Europa League trip to BATE Borisov on Thursday night, but when asked about the striker's separate regime, Sarri revealed an unusual change in the club's training methods.
Sarri has changed Chelsea training
"He [Morata] will not be doing weights," he told a press conference.
"Yesterday he had aerobic training. Five seconds, ten seconds, 15 seconds, recovery. Today he will have strength training - but we don’t use any weights.
"It’s all natural work that we do in the gym. Nobody does weights. I’ve never seen a player with a weight on the pitch.”
The Chelsea boss might well be onto something there. Instead, his players are focusing on cardio activity and stretching to tone their muscles.
It sounds rather unusual for professional athletes not to do any weight training, but it can't be said that his players don't look in peak physical condition.
Sarri has always been known as something of a maverick. He was still working in a bank at the age of 40, after all, so of course, he is going to have some unconventional methods.
There is definitely method in the madness.
