He said: “It is difficult to cover players like this with so much quality, you know you have to be close to them and not allow them to think, to try and keep his back to our goal.
“Kun is one of the better players but there is still time for him to be the best, he is very young, has a lot of quality and will become a big player.
“Atlético do not just worry me with Kun though but with the strong team they have. The power is in the collective with players like Simao, Maniche and [Diego] Forlán.”
