Nope Liverpool fan. Mascherano has for at least the past 5 years been an unsung player. For Argentina he is basically the captain despite Messi having the duty. Mascherano is often the player shouting around and organising and he keeps his position and will do a very good job 95% of the time. I enjoyed watching him back at Liverpool but he seemed to get pegged back by an ego. Since moving to Barca, that has stopped and in a sense, he has matured as a player.
That is the main problem with stats as well. Pogba is currently the 15th best player in Europe's top 5 leagues, when most of his stats are against the stat padder teams. He breaks down against the big teams and often goes missing. Adding Impact to stats would make them much better and context too. (Where have these stats come from, against who?)
