Soccer's the best. One of the reasons it's the best is that there are lots of leagues all over the world with lots of teams within them, and they all come together twice a year during the transfer windows to form one huge clusterfuck. Some of the richest clubs are owned by actual princes and/or oil tycoons, and there are no salary caps, and players, even the best ones, aren't traded but bought and sold individually like really well-trained livestock. Owners manage their teams like they're playing video games, and whenever they come in contact with other owners, they're compelled to swing their dicks around. This is one of those times.
Today's dick-swinging contest is the best dick-swinging contest, because it's between Spanish kings FC Barcelona, the greatest club of the last decade, and French champions Paris Saint-Germain. The two clubs have history: Just last season, Barcelona squeaked by PSG on goal differential in the Champions League quarterfinal. Barcelona are the most prestigious club in the world, and basically can sign whomever they want whenever they want. PSG, though, were taken over by a Qatari oil conglomerate Qatar Investment Authority in 2011, and now, without hyperbole, have more money than God. They're trying to buy silverware, and so far it's working.
