Jose Mourinho is preparing a squad overhaul at the Old Trafford this summer.
According to The Times, the Portuguese manager wants five big signings and is willing to renounce players he's found to be underperforming.
The trio - consisting of Porto full-back Diogo Dalot, Shakhtar Donetsk midfielder Fred and Tottenham's defender Toby Alderweireld - would cost the Red Devils £120m.
Further additions would be at left-back and central midfielder.
Defenders Daley Blind, Matteo Darmian and Luke Shaw are all set to leave Old Trafford.
Holding midfielder Michael Carrick has retired and will join the coaching staff, while Marouane Fellaini is expected to leave once his contract expires on June 30.
