Assuming that a match in the Western Division of the War League counts as a competitive game I'll select
Stanley Matthews, otherwise I'll select
Laurie Cunningham.
Link that shows that Matthews played for Manchester United in the War League
Anyone who wants to pick a 13th player can but you can choose to skip this pick if you like. I will skip the 13th pick.
I'll be using this extra selection.
