Real Madrid midfielder Luka Modric has backed Chelsea ace Mateo Kovacic to be his successor.

Modric is set to turn 37 in September, and appears to be aware that he is in the twilight of his international career.

Looking ahead to who could potentially replace him as Croatia's key man, Modric tipped Kovacic to continue to drive the team forwards.

"I think Mateo Kovacic could be my heir, at least he is the player with the most talent," he told Marca.

"He has played in important clubs such as Inter and Real Madrid. He is at Chelsea now and is doing really well.

"He is one of the possible successors. Surely he can lead Croatia in the future."
