This result marked a fourth consecutive victory for the Canaries and during that time they have only conceded one goal.
Race for Promotion: Bournemouth defeat slips them down to sixth
Wayne Rooney's first victory as the permanent manager of Derby County over AFC Bournemouth on Tuesday saw the Cherries slip down three places to sixth after Brentford, Watford and Reading all won their respective fixtures.
A Saman Ghoddos strike was enough to see Brentford secure a 1-0 victory over Luton Town which moved them up to third, while a Troy Deeney first-half penalty helped Watford to three points over Barnsley rising them up to fourth.
Then a very impressive 3-0 home win for Reading against ten-man Coventry City moved them up to fifth place, only three points adrift of the automatic promotion places.
Therefore, the Cherries' defeat at Bournemouth on Tuesday could be seen to be very costly especially considering that all of the teams apart from top of the table Norwich have at least a game in hand on Jason Tindall's side.
Next on the agenda, Bournemouth have a very pivotal encounter on the road to Reading and they will be desperate to earn three points, considering that they are undergoing a bit of bad form after only winning one of the last six league games.
Relegation battle: Derby move out of drop zone
Krystian Bielik's 32nd-minute strike at Pride Park on Tuesday saw the Rams move two points adrift of the bottom three into 21st position.
Bottom of the table Wycombe Wanderers were another team that did not feature during the week and with Derby's victory, they are now seven points away from moving out of the relegation zone but they do have a game in hand on Rooney's side.
Despite Nottingham Forest's recent good form - before yesterday, they were unbeaten in seven games - a defeat at home to Middlesborough moved Chris Hughton's side down to 20th now only five points adrift of the drop zone.
This can see seen to be a pivotal three points for Mark Warburton's side who now after their sixth league win of the campaign have moved up to 17th, seven points clear of the relegation zone.
However, this result extended Cardiff's losing run in the league to five games which is the first time they have undergone this much bad form since October 2018 when they were in the Premier League.
Finally, Scott Malone returned to his haunt his former club as his goal for Preston North End just before the half an hour mark condemned the Terriers to a fourth consecutive defeat in all competitions.
Meanwhile, these three points for Preston moved them up to 10th place in the table, only seven points adrift of the play-off places.
