Manchester United are struggling to agree new contracts with important players including David de Gea and Anthony Martial as a consequence of Alexis Sanchez's significant wages.
Sanchez is on a basic salary of £400,000-a-week at United and also receives £75,000 for each appearance that he makes.
As reported by The Mirror, the agents of players including De Gea and Martial, are using Sanchez's wages as a guide during negotiations over new contracts.
Both players' current contracts expire next summer but United have an option to extend their deals by a further year.
De Gea, widely regarded as one of the standout goalkeepers in world football, is currently on wages of £175,000-a-week.
The Spanish shot-stopper now believes that earning £300,000-a-week is not unrealistic for him.
Martial, meanwhile, currently earns £70,000-a-week, with United willing to double his wages, but an agreement hasn't yet been reached between both parties.
United have a host of other players out of contract next summer, with Juan Mata, Ashley Young, Antonio Valencia, Matteo Darmian, Ander Herrera, Chris Smalling, Phil Jones and Andreas Pereira all falling into that category.
Of those, United have an option for a further year on Valencia, Darmian and Pereira's deals.
