GSP or Anderson Silva? Elaborate?

For if there is likely to occur, but either St-Pierre has to gain weight or lose weight Silva, personally I would give my support to St-Pierre and hitherto invincible, standing far exceeds Silva but St Pierre has more physical strength, but many do not believe because it is thinner and dwarf, but I think it is stronger, which gives an advantage to take down Silva, but Silva has good defense Take Down, no think you can stop St-Pierre, and Pierre St-floor definitely it would end, this could even be considered as the best fighter of all time, if there are those who say that St. Pierre failed to knock Anderson Silva, and the Spider finished, in a nutshell is to support Silva, my support goes to George St-Pierre the best pound for pound the world.
