Arsenal will demand at least £50million for Alexis Sanchez, if the striker fails to sign a new contract.
Alexis, who has scored 23 goals and provided 12 assists this season, will have only one year left on his current deal in the summer.
Manager Arsene Wenger has already confirmed that talks over new contracts for him and Mesut Ozil, have been suspended until the end of the season.
His agents are reportedly asking for an increase in the 28-year-old’s wages from £130,000 to around £300,000.
The Gunners have already insisted that Alexis will not join another Premier League club if they have to sell, with Chelsea and Manchester City believed to be interested in the Chilean.
