Villarreal defender Pau Torres is a target for Arsenal.
The Sun says the Gunners are considering a January swoop for the Villarreal centre-back.
But getting the 22-year-old out of LaLiga will not be easy as Torres has a 43million release clause in his new contract.
That has not put off Arsenal, who are exploring a deal similar to the one that brought in Nicolas Pepe in the summer.
Lille accepted 20m up front for the Ivory Coast winger, with a further 52m to be paid later.
