“It's a privilege to play with Juan Mata and Hazard”
Chelsea striker Fernando Torres
"I've always been happy with Fernando," Di Matteo told BBC Sport.
"His workrate is immense and when he doesn't score he's a provider."
Chelsea maintained their 100% record with their third league win which moved them to the summit of the Premier League.
Torres's strike was his sixth goal in nine games for club and country. His early season form is in complete contrast with that of last season when he
went 24 games without scoring.
"The confidence is back because I'm playing more," added Torres, who also praised his support attackers.
"It's great to have players like Hazard here (£32m summer signing). It's a privilege to play with Juan Mata and Hazard."
Pardew blames tight schedule
Di Matteo also paid tribute to the former
Lille player Hazard,
who opened his Chelsea account on Saturday, and the rest of the team.
"It's good that he's scored a goal because he's helped create many for us," added the Italian, who has guided Chelsea to the FA Cup and Champions League titles since taking charge of the club last March.
"It's good to see us operate as a team. The midfield and defence also did well today."
Chelsea's next match is Friday's Uefa Super Cup against Atletico Madrid in Monaco.
"It's very, very important to play against my old team. It will be the first time I want Atletico to lose," added the Spanish team's former player Torres.
Meanwhile, Newcastle manager Alan Pardew said it was unfair that his side had to play two games in two days.

Newcastle manager Alan Pardew
The Magpies contested a 1-1 draw against Athens-based side Atromitos in the first leg of their Europa League tie on Thursday and had one day's preparation before travelling down to London for Saturday's Premier League match.
"It's not acceptable to ask professional football players to play two games in two days," said the Newcastle boss.
"We accepted it and didn't moan about it - but it always going to be difficult."
Chelsea dominated the first half, but Newcastle had the better of the attacking opportunities after the break.
"I'm proud of the second half - it was an outstanding effort," Pardew added.
"If we could have had a full week's preparation then you would have seen a different Newcastle."
