Not at all like Maradona. Maradona is a legend for Argentina, but has a reputation of being crazy and wild.
Batistuta is a legend and is known for being humble and successful. He never had any drug issues and was known and rated purely on his ability to score goals. I think it could prove to be an excellent appointment because of his status with the rest of the players (like Maradona), but then he will be able to provide tips for the strikers, whereas Maradona wouldn't have been able to do.
Also, Maradona was very popular among the players and fans, but one result cost him his job. I think he was fairly successful in his reign. Qualified for the World Cup (wasn't the best, but they got their) were rampant in the group stages, and then got out classed by a German side who also battered England and only just lost out to eventual winners Spain. His wild antics cost him the job in my opinion, not the sides performances on the pitch.
