Wenger has often picked English defender Kieran Gibbs over the 28-year-old left back, with his defending often under scrutiny.

The Spaniard only managed 23 appearances in the league last term, with half of them coming on as a substitute.

Meanwhile Arsenal have just lost consistent right-back Bacary Sagna to Manchester City, who left on a free transfer.

And Wenger is looking to replace the Frenchman with another La-Liga star in Joseba Zaldua.

The 21-year-old was promoted to Real Sociedad’s first team last season and impressed, interesting Wenger in signing him as Sagna’s replacement.
