"I've achieved a lot in Spain. It has been a useful experience to play for several different teams and move around. At Osasuna I had a difficult experience because of the relegation battle but I always had a place in the team.
"I played well all season. But I expect to have a much better season next year. I'm sure all my efforts will pay off.
"I'll be playing in one of the best teams in the world that plays competitions like the Champions League - I want those games as soon as possible. I have changed a lot, I'm more mature as a person and player.
"I feel ready for Arsenal."
