Taking in all competitions, where the two goalkeeper's minutes played are more comparable - Henderson's 1,695 to De Gea's 2,565 - Henderson's statistics are still impressive. He has conceded a goal every 130 minutes in all competitions, compared with De Gea's 69 minutes, and his save percentage is 79 per cent compared to De Gea's 65 per cent, with a win percentage of 68 to 52.
But has Henderson been tested yet?
Some will argue that Henderson has played lesser opposition in his 19 appearances for United this season, but two of his Europa League appearances have come against AC Milan, three of his six Premier League appearances have come against top-five sides (West Ham twice, Man City once) while five of his eight domestic cup appearances have come against Liverpool, Man City, Everton, Leicester and West Ham.
Taking a closer look at the type of shots both De Gea and Henderson face in the Premier League, however, show a stark contrast.
De Gea has faced 82 shots in the Premier League, with 38 per cent aimed at the bottom corners. He has saved 65 per cent of those.
Henderson, on the other hand, has faced 22 shots in the Premier League, with just 18 per cent in the bottom corners, saving 75 per cent. Incredibly, Henderson is yet to face a Premier League shot in the top corners, whereas eight per cent of De Gea's shots have been in the top corners, saving 57 per cent of those.
