The Belgium international struck in the first half of Thursday morning’s comfortable win over Seattle Sounders as the Blues’ US tour got off to a triumphant start.
"He [Hazard] can have a great impact in the Premier League next season. He has great qualities and you can see that everyday in training," admitted the Chelsea boss.
Di Matteo added: "It is good for Marko and Eden to score in their first game for the club and it was good to see they have a good understanding with their new team-mates.
"I’m pleased with the game and performance - it was everything we were looking for from our first pre-season game, it was a good work out.
"I felt we showed good energy, the new players integrated in well and showed the talent coming through can be the future of this club."
