The Barcelona-Real Madrid rivalry is one of the best in the world. With so many different personalities involved, it almost resembles pro wrestling. One of the best rivalries ever in pro wrestling happened in the late 90's when the New World Order (NWO) took over WCW.
The NWO were a bunch of heels (bad guys) who infiltrated a company of good guys that was the WCW. In this scenario, this obviously makes Real Madrid the NWO. Here is comprehensive proof to the point.
During last night's Champions League quarterfinal match between Los Blancos and Wolfsburg, this ugly incident between Maximilian Arnold and Marcelo happened.
