But while United have targeted two established talents in England's top flight, they are said to want to go one step further by eyeing players who have proven they can thrive together.
Because now it is claimed that the Red Devils want to partner Mbeumo with his former Brentford teammate, Ivan Toney.
Old Trafford chiefs are reportedly in talks with Toney's representatives to gauge his interest in a potential return to England.
United are allegedly weighing up a £30m swoop for the Al-Ahli striker, who is vying for a spot in England's World Cup squad next summer.

Toney should be keen to return to his homeland for that reason, as he emerges as one of Amorim's options ahead of a striker pursuit.
And United's possible pursuit promises to harvest success, given the 29-year-old and Mbeumo's track record while playing together.
Toney left Brentford for Saudi Arabia last summer in a move worth £40m, but Mbeumo has still played more games with him than any other forward.
The duo combined for 16 goals in 119 shared appearances for the West London club. Mbeumo has only sparked more fireworks with Yoanne Wissa, combining 17 times in 108 outings.

Given Toney's age and likely eagerness to make a Premier League comeback, he should represent enticing value compared to alternatives.
United need to sell players to fund any more signings after Mbeumo, making a third mega-money attacking arrival unrealistic.
Viktor Gyokeres would prefer to join Arsenal, Victor Osimhen's wage demands are too high, and Hugo Ekitike's valuation is beyond United's means.
Reuniting Toney and Mbeumo at Old Trafford could harvest more fruit than them all if the pair cracked on where they left off.
