Marko Arnautovic is demanding a massive pay-rise at West Ham.
The Sun says the Irons may have to pay £200,000 a week to keep Arnautovic.
That is the staggering figure being quoted to the club as they battle to keep their unsettled striker happy.
The Austrian, 29, is contracted for another four-and-a-half years on £130,000 a week and club insiders feel he is after one final big pay-day.
Hammers chiefs will refuse the £10m-a-year salary as it would shatter their pay structure and upset the dressing room.
Arnautovic said: “It's clear I want to compete with the best players but in this affair I totally trust my brother."
