Once upon a time, Nicklas Bendtner seemed to have it all as a sportsman. He was young, he was in love, he was a hot soccer player, he had a baby with a gorgeous incredibly rich woman, he was an important prospect for Arsenal -- sky was (or seemed to be) the limit.
He's only 28 years old, and still appears to be a decent player, if he could stop being a naughty boy. He's still listed on Denmark's World Cup team, so I assume he will still want to play for them. If nothing else happens in Europe for him -- he may have burned his bridges -- he could still end up in the MLS.
