Mateo Kovacic is happy at Real Madrid, insists his agent.

The Croatian continues to excel whenever he's given the chance and is always ready to slot in when called upon by Zinedine Zidane.

"Kovacic is very happy in Madrid, I can assure you," Nikky Vuksan told Fcinternews.it.

"I have total certainty that the club is very happy with Mateo and his contribution to the team.

"I don't think Mateo is playing very little, Madrid is the champion of Europe and has the best players in the world.

"And that means they have the best midfield in the world with players like Kroos, James or Isco."
