Speaking to Arsenal.com after completing his move, the midfielder said:"I think that’s a big part of my game and that shows the character that I have. I want to fight for every ball and this is something that I learnt when I was really young. Maybe you can win it, or you won’t. I’m not promising I will win every duel, but what I can promise is that I will fight for every ball with 100 per cent.
"It’s always tough to talk about myself in those kinds of terms, but I think I’m a hard worker, I want to call myself a good teammate. I like to work for the team with or without the ball. I’m always thinking about the collective aspect of the game. I like to play with the ball, I have a Spanish culture of football."
When asked if his experience with the Magpies will help him to adjust quicker to the Premier League, the player added: "I think it will be massive, because of how tough this league is if you come as a new player. Maybe you don’t realise it until you try it. But right now I have an idea of how this league is and how tough every game is.
"Obviously talking with teammates, or ex-teammates who are here, I know how high the standard is right now. You have to win every single game. I have a little idea of the stadiums, the teams, the atmosphere you are about to expect, it’s always an advantage."
