Messi is roughed up here and there, but the level of violence in football today cannot be compared with the 80s. Maradona's ankle was broken by a guy nicknamed "the butcher of Bilbao" (Andoni Goikoetxea) who also virtually ended the career of the German international Bernd Schuster. This type of player would simply not be allowed on the pitch today. It's incredible how Maradona came back from such a horrendous injury just in several months.

He did play for Barcelona, but Barca then was nowhere near what they are today and Maradona was injured/sick for extended periods of time, so he didn't manage to leave an inprint while playing there. His crowning achievements are the 1986 World Cup which he won almost single-handedly (as mentioned - Argentina's team was not very strong then - anyone remembers Jorge Burruchaga or Ricardo Giusti?), and the serie A titles with Napoli (again - won almost single handedly - the best Napoli players of the time were Salvatore Bagni, Ciro Ferrara, Fernando di Napoli, virtual unknowns today). What was impressive with Maradona is - first of all - his bravery as a player (one of the most kicked and beaten-up players ever) and the capacity to win single-handedly in a team sport which is amazing. Messi definitely does have some of the second (winning games almost single-handedly), but in my opinion, not yet at the same level.
One thing that is strange with Messi (but also with Ronaldo) is how few injuries these high profile players pick up today, even with all the protection allowed to them by the referees. They are either made of rubber or the medical staff in Barca and Real perform absolute miracles on them.
