Jose Mourinho has been under pressure and scrutiny from both fans and the board in recent weeks, after fallouts with key players Paul Pogba and Anthony Martial, as well as suffering defeats to Brighton and Tottenham Hotspur in the early stages of the season.
According to 'The Mirror', Zidane's targets would include Real Madrid's Toni Kroos, Bayern's Thiago and James Rodriguez, and PSG and Uruguay talisman Edinson Cavani.
It is unlikely the 'Red Devils' would be able to acquire all these targets, and bringing in star names has proved an issue for the club this summer after failing to sign Toby Alderweireld and Jerome Boateng.
Zidane won his third straight Champìons League trophy with Real Madrid in May, and has proved a serial winner with La Liga, the UEFA Super Cup and the Club World Cup all under his belt as a manager.
Manchester United continue their season next Saturday, after the international break, away at Vicarage Road against Watford.
