United are desperately trying to make late additions to their squad after a frustrating summer transfer window where they have failed to sign Erik ten Hag’s first choice target Frenkie de Jong.
Rabiot has emerged as a surprise option with United agreeing a fee in the region of £15million with Juventus for the 27-year-old.
Negotiations over personal terms are ongoing but Macari has shared the scepticism felt by many United supporters who have been left feeling decidedly underwhelmed by efforts to sign the Frenchman.
Macari was an MUTV studio guest during United’s live coverage of ten Hag’s press conference on Friday.
After the United boss had addressed the media, Macari discussed United’s transfer business where he delivered his damning verdict of Rabiot and the club’s failure to identify better options.
He said: ‘I’d never really heard of him [Rabiot]. Clubs spend millions of pounds scouting players across Europe, but nobody else has made a move for this fella. Why do you think this is?
‘I have got a bad feeling about the guy.’
United’s football director John Murtough was pictured in Turin on Friday morning as the club seek to push through a deal to sign Rabiot.
While a fee has been agreed with Juventus, United are still to agree personal terms with Rabiot’s mother and agent Veronique.
Rabiot broke into the Paris Saint-Germain team at 17 years old but endured an acrimonious departure from the club, joining Juventus in 2019.
The France international has just one year left on his contract with the Italian giants with United hoping to make him their fourth signing of the summer.
In addition to midfield reinforcements, ten Hag still wants a versatile winger and another striker this month.
United have explored a deal to sign former West Ham striker Marko Arnautovic from Bologna only to end talks after a fierce backlash from supporters.
