Speaking to reporters, Merino said: "It's been a very nice year. I'm seeing things I've never worked on before in my career, and it's also helping me learn about football and grow. Arteta is a very complete coach. He's taken the best from Guardiola, and you can see that period he had with him every day.
"The idea is to be a dominant team, one that carries the weight of the game and doesn't let the opponent have the upper hand. To subdue them and greatly limit their attacks. Then I think he also has his touches, his methodology, and that's what the best do: take the best from each position. And I think he's, if not the best, undoubtedly one of the best coaches in the world."
