"Man Utd" team is starting to worry about goalkeeper David De Gea's passivity.
"Red Devils" want desperately to sign a new contract with the 28-year-old Spaniard and are offering him a whopping £350,000 per week salary.
However, even insane amounts of money do not tempt De Gea for now - he is delaying signing a new contract and could become a free agent by 2020.
"Man Utd" team will have to make a decision - whether to continue improving the offer or to consider selling the Spaniard while they still have a chance to get a big transfer fee.
