The midfielder struck in the 1-0 Champions League win over Sporting CP.
Terry told Chelsea TV: "I thought he (Matic) was superb. Gary (Cahill) and I were saying how good he is sitting in front of us, breaking things up.
"He's also got a burst of speed when he gets it and dribbles through.
"He's come back a complete player and we're delighted he got on the scoresheet."
