The Times says uncertainty over United's participation in next season's Champions League has seen Pogba and De Gea both demand huge pay rises.
Failure to qualify for the elite European club competition would see every United player have their basic salary reduced by a whopping 25 per cent.
Pogba is on a £290,000-a-week deal and has two years left to run on his current contract at Old Trafford.
Meanwhile goalkeeper De Gea, who has endured a tough time on the pitch of late, has been locked in talks over a new contract for some time now.
The Spain international is looking for an improvement on his current £200,000-a-week deal, and his representatives are agitating for a higher basic salary.
