Maurizio Sarri made an instant impact as new Chelsea boss with a 3-0 win at Huddersfield in his first game in the Premier League - and he said his team still have a lot of improvement in them.
Much was made of the troubles Sarri had to deal with at Stamford Bridge, especially after their 2-0 Community Shield defeat to Manchester City.
Sarri also lost first choice goalkeeper Thibaut Courtois but replaced him with £70m man Kepa Arrizabalaga, who made an untroubled debut at Huddersfield.
After watching N'Golo Kante, Jorginho and Pedro secure the perfect start to his Chelsea tenure, Sarri said there was much more to come from a side he's only been in charge of for 28 days.
"I'm very happy for the three points," Sarri told Sky Sports. "For us, in this first part of the championship it's not very easy to gain points. I think in this moment we are not at the top of our potential.
"The first half was hard. If you look at the result, you can think about an easy game, but in the first half we were in trouble for 15 minutes against a very physical team.
"We are not a physical team and I think the best of the game is the capacity of suffering for 15 minutes. Then I think in the second half the opponents were a bit tired and it was easier."
Two months until Chelsea get going
With players coming back from the World Cup and some transfer upheaval, it's not been plain sailing for Sarri and he says it could take up to two months for his team to be playing in his own style.
"The situation until now has been very difficult," said Sarri.
"On Monday four players from the World Cup arrived [in training]. And then on Tuesday another two, so it's not been easy for me at the moment."
Asked how long it would take for his team to get up to speed - he responded: "It depends on me and the players. I don't know. Hopefully two months and not three.
"I have to know the characteristics of the players. I have to adapt myself to the characteristics of the championship and the players. Now I study my players."
