Maurizio Sarri has opened up on his astonishing attention to detail as he bids to make Chelsea a force in English football again.

The Italian has revealed he spent around 13 hours a day over the international break watching videos of opponents in a bid to gain an advantage.

Chelsea have won all four games under Sarri so far but he wants more from his side and has painstakingly looked for weaknesses in the opposition, with Saturday’s opponents Cardiff City among those targeted.

“We have to play seven matches in 23 days, so I had to work,” he said. “I have seen a lot of matches, of Cardiff and PAOK, West Ham and Liverpool, so I had to work.”

“Sometimes I’m working at the training ground, sometimes at my home.

“They were long days. But, for me, it's a pleasure. I am not able to think about this as a job, like work. It's 12 or 13 hours, but for me it's not working.”

Sarri already feels like he has settled in this country after three months into the job and he has now moved out of a hotel into his own house in Surrey.

“For the moment, I'm really very happy to stay here,” he said. “I have my dog here with a very big garden, so the dog is very happy. I'm really very happy. I feel like at home. I feel in my home.

“I have a house five miles from here, no more. It’s in Surrey, similar to my name.”

Sarri is not prepared to allow any dip in standards, revealing that while Napoli manager his side’s form used to fall after the international break.

“I’m not really relaxed as Cardiff is a very difficult game, a very difficult match,” he said. “I remember in my first season in Naples, the average points per match during the season was 2.28, I think. But the average after the international break was only 1.31 or 1.32.

“So I know that the matches after the break are very, very difficult. Fortunately in the last season, the average was the same: 2.4 in the season, 2.45 after the break. Only because after the first season the players understood the difficulty of this kind of match.

“I'm trying to stress this number to my players. Just telling them this number. My experience in this situation.”

Chelsea vs Arsenal Player Ratings 18-08-2018 Show all 22 1 /22 Chelsea vs Arsenal Player Ratings 18-08-2018 Chelsea vs Arsenal Player Ratings 18-08-2018 Kepa Arrizabalaga - 6 Could perhaps have been able to do more to stop Mkhitaryan’s strike in the first half. The ball was hit hard and low, he got a hand to it, but it still went in. A stronger arm may have kept that one out. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Cesar Azpilicueta - 5 Absent for the first half and rarely got forward. Arsenal had a lot of joy on both wings and were able to get to the left byline far too easily. To say he’s struggling to play in a back four would not be an understatement. AFP/Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 David Luiz - 6 Started a lot of forward moves by attacking the space in front of him and getting Chelsea playing from the back. His defending, like Chelsea’s, was a little ropey. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Antonio Rudiger - 5 Chelsea defended really poorly as a team, and Rudgier was no exception to this. Arsenal FC via Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Marcos Alonso - 7 Showed good awareness to pick out Pedro for Chelsea’s opening goal. Like Azpilicueta, he looks like he is continuing to adapt to playing in a back four, and while his attacking play is very good, he does look a little exposed. Showed composure to score the winner. AFP/Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Jorginho - 8 Justifying his lofty price tag. He dominated the game from midfield and did so without really breaking a sweat. His range of passing was so precise and varied. Arsenal left lots of gaps in their defence and he found all of them. AFP/Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Ross Barkley - 6 Was lively and popped up in some good areas for Chelsea. Sarri has a lot of faith in the English midfielder, and Barkley almost repaid him with a goal from range but Cech was equal to his effort. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 N'Golo Kante - 7 Another typical Kante performance, he was everywhere. Sarri seems to be giving him more attacking responsibility, that’s increasing Chelsea’s options in the final third and helping them win the ball high up the pitch. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Willian - 7 Is continuing to produce some really good stuff under Sarri, now he’s sorted himself out at Chelsea. His movement had his markers chasing shadows all evening. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Pedro - 7 Like Willian, he was very tough to track for the Arsenal defenders, although he often left his defenders a little exposed, but who didn’t? Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Alvaro Morata - 7 Scored his second league goal of 2018 and you could tell how much it meant to him by his celebration. He ran at Mustafi one-on-one, worked the ball onto his right foot and slotted a finish into the bottom corner. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Petr Cech - 6 Made a handful of good saves to keep out Chelsea’s shots from range. There was precious little he could do about any of the Chelsea goals, and was better with his feet than last week. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Hector Bellerin - 4 Made a hilarious attempt to defend. Was exposed by Alonso, Pedro, Hazard, and anyone who wanted to get past him really. His forward play, however, was very good and he got into some very dangerous areas. AFP/Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Sokratis Papastathopoulos - 6 Made some vital block and interceptions, but he cannot score highly and be part of this Arsenal defence. That’s not happening. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Shkodran Mustafi - 5 Continues to make you wonder how he’s managed to play at the top level for so long. Let Morata cut onto his right foot in the area, which resulted in his goal. Arsenal generally were a mess at the back and he has to take responsibility. AFP/Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Nacho Monreal - 6 Got into some really dangerous areas and created some very promising chances for Arsenal. His defending, however, was about as committed as Ozil’s tracking back. AFP/Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Granit Xhaka - 4 Picked up a yellow card in the first half and came off at half-time. Chelsea’s attacks passed him by and he didn’t have much of a say when Arsenal were in possession. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Matteo Guendouzi - 5 Unai Emery has certainly shown a lot of faith in the youngster, but you feel there are better options. He was dispossessed a couple of times in dangerous areas, but continued to show adventure going forward. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Henrikh Mkhitaryan - 7 Minutes after missing a sitter he took his goal very well. He started Arsenal’s first half comeback with a sweet low, curling effort from the edge of the area. AFP/Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Mesut Ozil - 5 One of Ozil’s ‘missing’ games. He came off after 70 minutes of not really doing an awful lot at Stamford Bridge. He played almost as a second striker, but no matter how hard he tried, there was no space for him in the final third. Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Alex Iwobi - 7 Took his goal very well, but that was the extent of his good work. A lot of his play ended with a wayward pass, a tackle or a shot going wide. Arsenal FC via Getty Images Chelsea vs Arsenal Player Ratings 18-08-2018 Pierre-Emerick Aubameyang - 4 Missed two sitters, and we’re talking proper sitters, in front of goal. If he scored them, we could well be talking about an Arsenal win. The timing of his runs was also off, he was caught offside more times than he needed to be. Can do better. Getty Images

Sarri is certainly a different character to that of his opposite number in the dugout on Saturday, Neil Warnock. The Cardiff manager is known for his passionate style which includes several YouTube clips of his infamous half-time rants.

“I’d only behave like that if it was necessary to gain points,” Sarri said. “I don’t think so.

“I’ve not seen the clips. I want only to see the team. I wanted only to study the team, the opponents and the match. Not other things.”

Meanwhile Sarri has not assessed how proposed new Fifa regulations limiting a club to eight loan departures a season will impact Chelsea.

The West Londoners currently have 40 players out on loan, but Sarri said: “I don't know anything about the new rules of Fifa.”

“There is something similar in Italy. For example, I think Juventus have about 45 players (out on loan). I don't know if the major part of the loans are in the same country, but I think not. If you have young players on loan in other countries, I think it's normal.
