The Canaries dominated the first half and led when Emi Marcondes put them ahead inside five minutes with a simple close-range strike following a Schwartau cross.

Managerless Milwall, who drop to 13th, one point and one place below their hosts, failed to register an attempt on goal before the break and trailed 2-0 when Danish striker Schwartau tapped the ball home for his first Norwich goal.

The second half continued in the same vein, with the hosts bossing possession and going close to adding to their tally, notably when a Schwartau strike came back off the post.

Romain Esse's fine low strike from the edge of the area - Millwall's first strike on target - ensured a nervy finish, but Norwich deservedly held on.
