Juventus star Douglas Costa has revealed he's still in contact with Pep Guardiola.

Costa signed for Bayern Munich to work with Guardiola and admits he's still speaking with the Manchester City manager.

"Guardiola is unique," said the Brazil international.

"In my opinion, he is the best coach in the world. I appreciate him very much. We are still exchanging messages."

Costa joined Juve from Bayern last summer on-loan.
