It was a vital stop, and he absolutely deserved the golden glove over Lloris for it.
I’m not sure I see how it counters my argument though - had Martinez let everything past him for the first 80 minutes (not that France actually had a shot during that time, but hypothetically) whilst an excellent Argentine attack kept it level, that save alone wouldn’t cement greatness as the rest of his performance was subpar.
This is essentially the crux of my argument regarding Mbappe, he was far too quiet for far too long and didn’t play for the team often enough to deserve such plaudits.
