Emery is adamant Spanish football remains at the pinnacle of the game.
He told ProLiga: "We have exported a lot of success. We have the two best teams in the world, the National Team has also shined in recent years...
"We have a great methodology and that must also be maintained.
"Their customs are different, we must acclimatise (abroad).
"You have to be able to contribute and collect also from there. The language is essential, the relationship between coaches and players is very close."
Interestingly in England, Emery's problems at Arsenal were blamed on his English language difficulties.
