Belgium's World Cup 2014 squad does have a place for Manchester United man Adnan Januzaj but Radja Nainggolan will only be called up if there's an injury.
Nainggolan became known with his performances for Cagliari where he played between 2010 and 2014 after joining from Piacenza.
The Antwerp native then moved to Roma in January on loan with the option to make the deal permanent in the summer.
It has been a positive spell for Nainggolan at the Stadio Olimpico and he has played a significant role in Roma's excellent campaign.
But it was to be a disappointing afternoon for the 26-year-old as he was only picked on Belgium's stand-by list and looks likely to sit out the World Cup.
There was space for Napoli winger Dries Mertens in Marc Wilmots' squad and also for Adnan Januzaj who recently committed his international future to Belgium although he could have represented England, Albania, Kosovo, Serbia or Turkey.
While Wilmots' decision was probably made simply for football reasons, it has been suggested in the Italian media that Nainggolan's tendency to argue with critics on Twitter may be a factor.
Roma have encouraged Nainggolan to use Twitter sparingly but he remains active and his frequent controversies on the site may be an argument for not taking him to Brazil.
