In his time at Feyenoord, Mtiliga was touted as a coming Danish international by manager Ruud Gullit . Though he played well for NAC Breda, he felt overlooked by the national team in spring 2008. In November 2008, he was called up for the senior Danish national team by national manager Morten Olsen. He made his debut against Wales, but was then dropped from the national team. In May 2010, he was included in Olsen's preliminary Danish squad selection for the 2010 FIFA World Cup. Although his inclusion came as a surprise to some, Olsen found that Mtiliga's move to Malaga had improved his competitive level.
