I dont think Argentina needs Maradonna as their coach. He was great as a footballer but, he may not a be good coach. Argentina has the most gifted players at the moment and all argenina needs one tactically genious coach. I dont think Maradonna has that.
Bekenbauer was a much better footballing brain and Klinsmann has Löw who is an absoulte tactica genious. So can realyl compare them with Maradonna. Argentina needs a iron man .. not a over emotional coach.
