Arsenal are ready to take up their option to re-sign Carlos Vela but remain in negotiations to sell him back to Real Sociedad or potentially another European club.

As part of the deal that saw Vela join Sociedad in 2011 for £2.5 million, Arsenal negotiated a buy-back option that allowed them to re-sign him at the end of his contract for £3.25 million.

Vela has had a productive three seasons in Spain, scoring 36 goals and would surely have a higher resale value than the £3.25 million fee that Arsenal would have to pay.
