Spain coach Luis Enrique has thrown down a challenge to Manchester City boss Pep Guardiola.

The pair are former Barcelona teammates and good friends.

Enrique stated: "He is the best in the world because of his ideas, some say that with these players everybody would be able to win, they also said this to me about my Barça and the trident.

"But there are coaches who do not know how to manage a crack. Before he retires I would love to see Guardiola at Celta or Sporting, he would not win the Liga but he could show that he can make a team play how he wants."
