Arsenal goalkeeper Emi Martinez says manager Mikel Arteta will soon develop into one of the best in the world.
Arteta led Arsenal to FA Cup glory this season - his first as senior manager.
And Martinez told Marca: "Arteta is a great coach, he changed the structure of Arsenal, he gave us a game plan. He is one of the best modern trainers today.
"In six months he has won a title, no more nor less than the FA Cup, one of the best cups in England and one of the oldest in history.
"He has a great game idea. He's very smart, in my opinion, he's going to be one of the best coaches in the world. I have no doubt that he can lead the Spanish team.
"(Pep) Guardiola said that everyone at Manchester City had learned from Arteta. In training we see that he has a clear idea of the game, he surprises us day by day."
