Real Madrid loanee Mateo Kovacic says he is very happy with life at Chelsea.

But the Croatian central midfielder admits that he does not know where his future lies.

The Blues do NOT have any agreement to sign him permanently from Real when his loan expires at the end of the season.

"I wanted to be happy and at Chelsea I am," he said in an interview with Marca.

"I just wanted to be happy and play matches, feel a responsibility within the team and I've found that at Chelsea. This is not the time to talk about anything other than playing and enjoying.

"I don't want to think about what will happen and do want to be happy doing what I like, which is to play football every week."
