The Reds have banged in eight goals across the festive victories over Cardiff City away (5-1) and at home to Huddersfield Town (3-1), representing a big increase on the 1.7 goals per game average in the previous 17 Premier League fixtures this season.
However, the consecutive run of top-flight matches in which United have conceded was stretched to five by Victor Camarasa's penalty in South Wales and then six when Mathias Jorgensen stabbed home an 88th-minute consolation for our Boxing Day visitors following a free-kick.
Amid all the new-found positivity under caretaker manager Ole Gunnar Solskjaer, the lack of shut-outs seems a very minor negative but it's nevertheless still one that Shaw wants to nail, if only to give the United defenders a badge of honour for their otherwise excellent efforts.
