The Sun says Sanchez, on an eye-watering £505,000 a week, picks up a staggering £75,000 per goal, with an extra £25,000 each assist.
And World Cup winner Pogba is paid £50,000 for every goal and £20,000 for each strike he sets up.
But United team-mates do not have the same incentives in their contracts and are on a fraction of the mammoth money Sanchez and Pogba can earn.
Now Red Devils boss Ole Gunnar Solskjaer is battling against jealousy and rifts in his squad.
The bonus system could be one reason Sanchez and Pogba squabbled over taking a spot-kick against Leicester.
