The 30-year-old Spain international, though, would be keen to stay in the deeper position he is in now.
"It's a position I really like, though of course it means I'm further away from the opposing area so I have fewer chances to score. I'm finding my best form and I'm really enjoying the new position," he told the club website.
"You have different responsibilities. In terms of defence, you have to defend more and you have to help the team more in terms of making sure you're well-positioned to ensure the players in attack can stay fresh.
"We need the likes of Mesut, Alexis, Ramsey, Oxlade-Chamberlain, Walcott and Giroud to be fresh - so that means myself, Coquelin, Arteta and Flamini need to be well-positioned to ensure those in attack can perform as well as possible."
