Manchester United reportedly decided against a move for Bruno Fernandes in last summer's transfer window as they were concerned about the Sporting Lisbon attacker's decision-making.
The Red Devils were strongly linked with the Portugal international ahead of the 2019-20 campaign but the transfer window closed without the club completing a deal.
Ole Gunnar Solskjaer's side are now believed to be on the verge of signing the 25-year-old, though, with the move potentially going through over the weekend.
According to Metro, concerns over Fernandes's decision-making and shoot-on-sight policy led to the 20-time English champions deciding against pushing to sign him before the start of the season.
The report also claims that United were not prepared to agree to a deal which could have eventually cost them in the region of £80m with various add-ons.
Should the attacker complete a move over the weekend then he could, in theory, make his debut against Burnley in the Premier League on Wednesday night.
