Ole Gunnar Solskjaer wants Manchester United to break their transfer record twice this summer.
The Norwegian wants a total overhaul of his defence after finishing sixth in the league last season.
The London Evening Standard says Solskjaer has informed transfer chief Ed Woodward of his desire to sign Harry Maguire and Aaron Wan-Bissaka.
Crystal Palace are holding out for as much as £60m for England U21 international right-back Wan-Bissaka, which would make him the most expensive defender in the club's history.
Meanwhile, Leicester City want United to pay £80m for centre-back Maguire, once again breaking the club's transfer record for a defender.
