Just no. Leaving aside team achievement (which would complicate the reasoning, as how can you judge a player as Johann Cruijff, which is not only one of the greatest in football history but also a legend when you look at Ajax history?), if we consider just the individual skill, it's very hard to pretend that Messi is better than Maradona or Pelè.
Heck, I would say that Garrincha was more skilled than Messi: Garricha is considered to be the 2nd best brasilian player after Pelè, and in the top 10 of all the world ever. If you consider that a series of birth defects left him with a deformed spine and a left leg that was six centimeters shorter than his right one, that's a crazy achievement.
