'Fiercer' may be the wrong word, but the image (hilarious though it may be, looks like his jaw is melting off in anguish π ) makes my case for me.
That's one of the world's greatest footballers crying publicly because he didn't win. Not resigned, not lazily blaming his team mates (perhaps angrily, but not lazily), not looking to the next club, beach holiday, or cup comp, not drifting out of the game absent-mindedly. Torn because he lost. It's an attribute worth having.
