From a football perspective, it could be trouble. There is only one ball, so three top forwards Messi, Neymar, and Suarez might not work. Just like in the NBA, having three guys on the court who want the ball and to shoot can lead to disaster.
Good point. I’m far from an expert about soccer, but it seems to me that the current World Cup has made it clear that team chemistry is really important, and that having high profile players is not enough to bring a championship.
