The coach has praised the attacker's "balls" and work ethic, and hopes a deal can be struck to keep him at the Emirates Stadium
Robert Pires has revealed that Arsenal star Alexis Sanchez is not sure of renewing his contract with the Premier League outfit.
The Chile international has been a key component of Arsene Wenger’s side so far this season, netting 17 times as they have established themselves in the top four of England’s top flight and progressed once again to the Champions League last 16.
But his failure to extend his stay at the Emirates Stadium, which is currently due to end in June 2018, has been the source of some concern among the club’s support, and even Pires has confessed that the player is not certain he will be put pen to paper.
