Former Monaco and Spain coach Robert Moreno believes Aurelien Tchouameni could be one of the "best midfielders in the world for the next decade".

The Monaco star is expected to complete an €80m switch to Real Madrid.

"They are talking €80m so I will be waiting for a thank-you message," Moreno tells Sky Sports.

"He has become one of the best midfielders in France.

"He has become the player we expected."

Moreno added: "Tchouameni is a different player because he understands football.

"When you talk with him, you realise this. There are those players who just play. Players who can't explain what they do. He is always analysing what is going on and what is going to happen.

"That is why I think he is one of the biggest talents. He is strong but technical. He is a complete player. I think he will keep improving. He could stay at Real Madrid for years and go on to become one of the best midfielders in the world for the next decade."
