Despite Gary Cahill, John Terry and Kurt Zouma being above him in the pecking order at the club, Miazga has admitted he will continue working hard to try and secure a regular spot at the heart of Chelsea's defence this term.
"It was a good debut for me," Miazga told the club's official website.
"I'm happy to contribute to the team and now I have to work hard in training to keep trying to get more chances.
"I found out in the morning I would be in the starting XI.
"It's my job, my profession and I have to be ready when I am called upon and show the manager I can contribute and help the club."
