It doesn't matter how it's reported thats just pedantics. When people are disgusted at the wages they don't care how the non-performance related criteria is reported they care what's fair earnings overall.
Image rights are guaranteed and as for loyalty bonus it's basically fulfil this contract you're getting (and you don't even have control over that) and you'll get paid which sounds an awful lot like a salaried wage.
If it's 150k per week for non performance related and then the rest is performance tied that would be on the high side but fair if we're expecting him to be our key striker with 20 plus goals.
What is fair earning? Why should average fan care about it when they have no idea how the contract is structured?
Again, anyone knows what's the base salary and how much is the bonus? Telegraph report itself said "The contract is understood to be heavily incentivised
" so where is this assumption that what money is base salary and how much is performance bonus coming from?
You just came up with random number 200K + bonus earlier and now you are setting up some sort of fair deal saying if his contract is 150K + 150K (performance bonus) then yeah it's a fair deal.
Once Martial signed huge contract, this was always on the cards. Again, unless his contract is leaked, no one knows just like how Lukaku had 4.5 million bonus for scoring + assisting 50 goals, which he will never get at ManUtd. For all we know, his contract is linked to ManUtd winning major trophies and him scoring shit loads of goals, if that's the case he deserves whatever he gets.
