The former Bayern Munich midfielder insists he's be welcomed warmly by his new teammates.
He told Sport: "It's a squad formed by extraordinary players, but I have also seen very good people who give the feeling of forming a family as a team.
"What the coach (Ernesto Valverde) wants is for me to help the team, to show everything I am, to be very focused on all the movements that the team performs, both in training and in games.
"I am ready to adapt and play in this team.
"I can help us win everything because I have been lucky enough to play with many different styles and it has not cost me much. And I hope that here it does not cost me."
