He is expected to be handed a boost to his £100,000-a-week flat-rate wage.
He does earn more in incentives and bonuses, but is still way behind David De Gea, Paul Pogba and Co.
Fernandes is one of the lowest paid first-team players at Old Trafford, and is keen on a pay rise.
It is expected his money will go up to around £200,000-a-week flat, with extras on top of that for appearances, goals and trophies.
De Gea is on around £375,000-a-week, Pogba about £290,000 with Anthony Martial slightly behind.
