Ralf Rangnick opted for 11 changes to the team that drew 1-1 with Young Boys in the UEFA Champions League on Wednesday, but stuck with the same side that claimed a 1-0 victory over Crystal Palace in his first match in charge last Sunday.
In an end-to-end game, Cristiano Ronaldo's penalty goal in the 75th-minute proved to be the difference at Carrow Road. The Portuguese superstar was brought down in the box and he duly smashed the spot-kick home to secure three important points.
However, a win would not have been possible without yet more outstanding saves from David De Gea, particularly in the game's final few minutes as the Canaries searched for an equaliser.
