Was Argentina Legend Diego Maradona Locked out of the Maracana at World Cup?

Diego Maradona claims FIFA denied him entry to Argentina's opening World Cup match against Bosnia-Herzegovina at the Maracana.

Said Maradona to Argentine TV station TyC, as per the Daily Mail:

I did everything I could but they would not let us in. Someone just said no, it could not happen, so I had to watch it on TV. 

Hopefully we will get this resolved because I want to go and see Argentina in several more games. It is one thing to not be able to go to a game, and another to not be allowed to go.

Here's how FIFA responded to the accusation, as per Guardian writer Marcus Christenson:

Who to trust? The crazed genius they call Maradona? Or the much-maligned institution we call FIFA?
