Andreas Cornelius says he moves to Cardiff City with an eye on the Denmark national team.
The 6ft 4in striker top-scored with 18 goals in the Danish Superliga last season, during which he also made his senior international debut.
He hopes his move will enhance his chances with the national team.
"The Danish national team always wants players playing in foreign countries, especially in the English Premier League," he said.
"If I can improve as a player at Cardiff City, which I think I can, then I can be a better player for the Danish national squad as well."
