The Gunners’ captain penned a new one-year contract not long ago, but with the Spaniard now 33 his time as a first choice player at a top club is limited.

A move for the 27-year-old would be somewhat ambitious, with the classy holding midfielder a first-team regular at one of the most successful clubs on the planet and an influential figure in the dressing room.
