Jose Mourinho's side scored two late goals to earn the points at Carrow Road, and Nevin believes that the result was a notable one, considering that they were heading to a 1-1 draw after 85 minutes.
"The win against Norwich was a pretty impressive one considering how things were looking with only 10 minutes to go," Nevin told the club's official website.
"First of all [Norwich manager] Chris Hughton had made some pretty impressive, if very defensive for a home side, tactical decisions in the second half.
"As they drove forward looking for the winner, the deep defending was forgotten and Chelsea broke twice in quick succession to devastating effect."
Mourinho's men are currently third in the Premier League, two points behind league leaders Arsenal.
