Juan Mata believes Roberto Di Matteo is the "perfect" manager for Chelsea as the Blues look to maintain their flying start to the season.
The Premier League leaders, who face Shakhtar Donetsk on Tuesday, have dropped just two points in the Premier League so far.
"I think for us, he's the perfect manager," Spain midfielder Mata said.
"Robbie knows the team very well, Robbie knows the club very well as well. He is a legend here.
"And now, as a manager, he connects very well with the team, in every meeting, in every speech, he goes deep inside every one of us, talking about every game."
Expensive summer signings Eden Hazard and Oscar have been key to Di Matteo's team's impressive opening to the campaign.
Mata, 24, who joined from Valencia last year, feels Chelsea have the right mixture of experienced players and talented youngsters.
"We have three or four players who are very, very important for us," he added.
"They are legends now at the club because of what they did during eight, nine, 10 years.
"We are now enjoying (life) with young and with experienced players and I think there is a balance that we have in the dressing room."
Di Matteo insists he is not concerned about receiving credit for the club's success since he replaced Andre Villas-Boas.
The Italian said: "I'm just happy to be leading this group and working with these players and working for the club that I have in my heart."
Shakhtar Donetsk boss Mircea Lucescu believes Chelsea will be made to pay for undervaluing former transfer target Willian.
The Blues were linked with the 24-year-old Brazilian in January and throughout the summer but he will line up for the Ukrainian side against Di Matteo's team.
Lucescu said: "Willian was far away from Chelsea. They didn't even get anywhere near to our requirements, having done nothing to make my promises to Willian come true.
"Speaking specifically about the amounts, they officially offered the sum for which we had bought him young.
"I would really like them to highly appreciate his true value tomorrow and realise that they made a big mistake."
