Fulham and Sunderland both suffered surprise defeats earlier in the day, but Daniel Farke's team had no such worries.

Gabriel Gudmundsson scored one and set up another as Leeds got back to winning ways after failing to win any of their last five matches in regulation time. 

Leeds needed penalties to get past Birmingham City in the fourth round, but Sean Longstaff's neat finish put them ahead in the 32nd minute here.

Having teed up Leeds' opener, Gudmundsson got on the scoresheet himself just before half-time.

Norwich improved in the second half, with Anis Ben Slimane almost making an instant impact from the bench, but he saw his shot cannon against the woodwork.
