Manchester United's owners have assured manager Erik ten Hag he will have the funds needed to completed his summer signing plans.
Ten Hag still wants to see a deal for Inter Milan goalkeeper Andre Onana completed and a new striker signed.
There had been concerns the Glazers would block Ten Hag's buying plans with talks continuing over the club's sale.
But the Mirror says the Americans know the club's value will drop without serious investment and that they must not fall any further behind Manchester City and keep pace with the rest of their top-four rivals.
Ten Hag went into the summer market expecting to spend 170m, with 55m now already spent on bringing in Mason Mount from Chelsea.
