The 'Daily Mail' reports that United are ready to follow up their big-money move for Romelu Lukaku with a further four deals.
Lukaku's arrival, along with the departure of Wayne Rooney, will not be the only significant transfer movement in the coming days and weeks.
United have their eyes on players from Chelsea, Tottenham and Inter Milan.
The club's number one target is Inter winger Ivan Perisic. The Italian club value the Croatian international at around €50m but United are believed to be repared to pay that amount in order to sign the former Dortmund man.
The next two players on Mourinho's wish-list are two of his former charges, Nemanja Matic and Willian, both from Chelsea.
The two players were key as Chelsea reclaimed the Premier League title last season, though Conte is believed to be willing to part with Matic as soon as he seals a deal for Monaco's Tiemoue Bakayoko.
The 'Dail Mail' reports that Conte would be prepared to let both Willian and Matic leave in a combined deal worth between €65m and €70m.
The final target comes as no surprise. Mourinho is a long-term admirer of Tottenham's Eric Dier, though as we reported earlier today Spurs are adamant that the player is not for sale.
After a slow start to their transfer dealings this summer it certainly seems that United mean business.
