Hart was visibly frustrated as England were sent back down to Earth. Many will have predicted their loss and the disappointment from some fans and pundits after the game seemed naive.
Roy Hodgson did well against a few mediocre teams and one with semi-professional players - with all due respect - but to compete against a nation that England should be matching would always be beyond him.
Yet goalkeeper Hart feels Tottenham's Alli and Dier represent promise for the Three Lions due to their youth.
Hart told ITV: "We’ve got people like Dele and Eric. I’m an old man but we have young players like them, that’s one promising thing."
The Spurs duo certainly do represent promise and so do England's younger players.
But promise is the best the Three Lions can ever manage. When it comes down to it, they will probably disappoint once again...
England face France next Tuesday night, although it's unclear whether things will proceed as normal after events in Paris on Friday night. If they do, Tottenham fans will no doubt look forward to seeing Alli, Dier and co in action once more.
