Alexis Sanchez wants pay parity with Mesut Ozil as he seeks a deal that will make him the equal best paid player in Arsenal’s history, Football Insider sources understand.

Sanchez and his representatives have begun talks with Gunners chiefs in the hope of reaching an agreement in the coming months.

A senior Arsenal source has told Football Insider that Sanchez wants a contract that will put him on a level footing with Ozil, who, as revealed by Football Insiderhas already agreed in principle a deal that will elevate his basic salary by £50,000-a-week to £180,000-a-week.

Discussions between the Chilean and the club are centred around a five-and-a-half-year agreement that will run until 2021 and could be worth a staggering £51.5million.

Sanchez has been a huge success at Emirates Stadium since his £32million move from Barcelona in the summer of 2014.

He has recently returned to action following a two month lay-off and is set to be in the team that faces Leicester in the Premier League on Sunday afternoon.

Sanchez currently earns £130,000-a-week, which makes him the club’s equal top earner along with Ozil. Only manager Arsene Wenger earns more than Arsenal’s two most expensive ever signings.

The Londoners are keen to tie down first-teamers aged under 30 to long-term contracts and the Sanchez contract situation is the latest on their radar.

The Chilean signed a four-year deal when he joined and it is due to expire in the summer of 2018.
