"Thanks to the great family of Almeria, all the coaches, the players, employers for your great support and affection towards me, and the opportunity you have given me to show my qualities in this first division."
"The only thing I can say is thank you, thank you and thank you. I wish you good luck to the club @udalmeria to go back to first."
