Casillas' future at Madrid is currently uncertain after falling out of favour under manager Carlo Ancelotti, with the Italian preferring Diego Lopez between the sticks. The Spain international, 32, is yet to feature in La Liga this season, but has continued as the club's first choice in the Champions League and Copa del Rey. Casillas' lack of consistent first-team involvement has seen him attract huge interest from a number of Europe's leading clubs, including Arsenal. Gunners star Cazorla admits he wants his national counterpart to join him at the Emirates Stadium, but is well aware of the difficult decision facing Casillas - who has spent his entire career at the Bernabeu.
