Barcelona ace Leo Messi is full of praise for Manchester City boss Pep Guardiola.
Messi won the Champions League with the Catalan.
"Guardiola was a unique teacher for me," the forward told Fox Sports.
"He is a coach who warns you of everything that'll happen in a game.
"I do miss Xavi and Andres Iniesta.
"I knew that we would win matches, no matter who it was against."
