Really don't get all the fuss, and a bit of perspective needed here.
Putting myself in Leo's shoes here - three years, three major international finals, three losses, two on penalties, one in extra time. The pressure he's under to emulate Maradona and the talent they have with nothing to show for it, hence his comment after the game.
Reaching a final is a rarity in itself, for example England haven't even been in one since we won the WC in 1966, over 50 years ago, so to reach that stage three times in as many years and lose in heartbreaking circumstances, i'm giving him the benfit of doubt.
Had he said 'Fuck this i've had enough' after Germany 2014, maybe the critisim would be fair, but not when you've lost three in three and your country haven't won anything for over 20 years.
