The World Cup winner is pleased to see a key man available for his country but believes the rescinding of his suspension shows preferential treatment
The Barcelona star has been cleared to play for his country again after sitting out just one game of an initial four-match suspension.
He has been cleared by the FIFA appeals committee after allegedly insulting a match official during a World Cup qualifier against Chile.
Maradona believes the complete exoneration of Messi sends out the wrong message to those who have committed similar offences, with the authorities displaying preferential treatment.
He told Radio La Red: "It makes absolutely no sense, but Leo deserved [to be sanctioned] for one more match and I say that with my heart in my hand.
"They reduced the ban for the same reason they always do with star players and veteran players
"Messi is not the type of player to insult anyone. I managed him for one year and he is more like a teddy bear than a football player."
An iconic figure added: "You have to congratulate all those who made it possible to get Messi's ban reduced.
"I am happy with the decision, both for Messi and because I am Argentine. We can return to dreaming about the World Cup again."
