Adnan Januzaj's decision to play international football for Belgium came from the heart, but a trip to Brazil in the summer is not guaranteed.
The Manchester United winger will play for Belgium, choosing them over Kosovo, Albania, England and a host of other countries interested in his services.
"Belgium is the most logical choice – he was born in Brussels, studied here and has his friends," said his agent, Dirk De Vriese, in interview with a Beligian website via the Guardian.
"His relationship with Kosovo and Albania made sure it was a difficult decision but his family supported whatever choice he made. But Adnan has not talked to coach Wilmots and has received no guarantee that he will be selected for the World Cup. He must first become a regular at United and then we will see what happens."
De Vriese also commented on Januzaj's emotional state after a hectic week at the club and country level.
"It has been an emotional week for him with the departure of coach David Moyes. Adnan is in his first full season and has been the only bright spot for United this year."
The teenager started 12 games for United this season, and made 11 appearances off the bench, scoring four goals.
