Belgium coach Roberto Martinez has explained omitting Adnan Januzaj from his preliminary Euros squad.

The Real Sociedad winger had expected to make the cut, but Martinez conceded he couldn't find room for him.

He said, "It was the most difficult decision because I appreciate his talent.

The competition is very strong (in his position).

"Adnan is not here because other players are better prepared than him at the moment, but he has a great future ahead of him."
