"We are all now glad that pre-season is over and we are looking forward very much to the new season and the game at Aston Villa," said the Basque midfielder.
"We have worked very hard now for several weeks and we are in good condition.
"Everyone is ready, and everyone is available. We have no injury worries and it is all now down to the manager's selection for the match.
"I know everyone is asking us already about the title race, and I understand that. But I would prefer to just consider each game and hope that we can put together the performances we need.
"Over the last three years we have sometimes lacked consistency away from home and we have not always started the season well.
"Now we have to look at those sort of games, and the way we start a season, and make sure we improve. I feel now that we have the squad to do that."
