Manchester United are hoping to seal three more signings before the transfer window closes.
The Red Devils have only secured Donny van de Beek for the first team.
The Dutch midfielder arrives to provide competition in those positions.
According to the Manchester Evening News, United want to sign Sergio Reguilon from Real Madrid, along with a centre-back and striker.
They do want Jadon Sancho, but may be priced out of a move for the Borussia Dortmund winger.
Their forward targets include Moussa Dembele, Joshua King and others.
It is unclear who they would chase at centre-back, but David Upamecano is a long term target.
However, the Frenchman may be pursued next term.
