Santi Cazorla is set to become the third senior Arsenal player to agree a new contract. The Spain midfielder has been in talks with club chiefs about signing an improved deal that will keep him at the Emirates Stadium until 2017 - his current contract ends in 2016 Sportsmail understands that Arsenal and Cazorla, who turned 29 in December, are close to finalising terms that will lift his salary to around £80,000-a-week. Cazorla’s new deal is set to be announced as part of a package with senior team-mates Per Mertesacker and Tomas Rosicky. Mertesacker, 29, has approved a new deal that will tie him to the club until the summer of 2017, while Rosicky, 33, has agreed a new one-year rolling contract. Arsene Wenger revealed after Arsenal’s victory over Sunderland last weekend that Rosicky had agreed fresh terms and it is believed that Mertesacker and now Cazorla are close to following suit.
