Lionel Messi "is not a leader", Maradona said in an interview to Fox Sports, adding, "It's useless to try and make a leader out of someone who goes to the bathroom 20 times before a game".
"I don't know if we're prepared and we don't have the history behind us to say if we are up to the mark".
Messi has not figured for his country since suffering a last-16 exit in his latest showing on a World Cup stage.
Interestingly, since Argentina's exit at the Mundial, Messi has blacked out Argentina games so far and no words yet when he return to action for the Albiceleste again. If he is not, we should try and play as a team and be hard to beat'.
The 31-year-old Messi has enjoyed a glittering club career with Barcelona, winning nine La Liga titles, four Champions Leagues and claiming the Fifa World Player of the Year award five times.
