The 19-year-old duo were part of a United team that was strong defensively throughout the 90 minutes apart from a few hiccups including the corner for West Ham’s goal.
Both could have been easily overawed by the occasion which was a real pressure game but they instead took it in their stride.
It was the perfect start for their United careers and Louis van Gaal will have been impressed with how they coped with the occasion.
Here’s what a few United fans thought of their performances and the reaction was overwhelmingly positive which is a testament to how well they both played:
Shaw and McNair had great debuts, looked really composed at the back. McNair also made a brilliant clearance off the line in the 2nd half.

Thought Shaw had a very good game today & Rojo looked much more comfortable centrally. Love Fletcher but he's not Utd level anymore IMO.

Missed the match but Twitter summary seems to be:
*McNair, Shaw, & Herrera outstanding.
