The Red Devils have been heavily linked with a move for Borussia Dortmund star Sancho this summer, though have been put off by the £108m price tag.
United are still hopeful of securing the English forward this summer though Ole Gunnar Solskjaer is reportedly looking at back-up options.
McNeil has caught the eye while at Burnley having been part of Manchester United’s youth team.
He was released at the age of 14 but is now regarded as one of the finest up-and-coming players in the Premier League.
And Lancs Live claim United are keen on re-signing the winger and he is on their transfer radar, though a deal is unlikely to happen if Sancho arrives.
Borussia Dortmund have remained firm in their stance that United missed the deadline to sign Sancho.
Though Bild's German football expert Christian Falk claims Sancho still wants to join the Red Devils, despite negotiations going quiet.
He told The Beautiful Game Podcast: "It's important for United fans to know that he still wants to go to Manchester United.
"It's just a question of money, if they pay €120million I think it's a crazy amount of money during this time.
"I know Ed Woodward gets plenty of pressure from the fans, perhaps he has to pay it. I think that many people didn't know that also Sancho signed a contract secretly which is one year more.
“For Dortmund there is no need to sell him now, they get the price next year also.

"Dortmund knows there is quite a promise, if a club bring the price and pay the €120million he can leave.
"He's already agreed to United so there are not any other clubs in for him. Of course it's always a risk to wait one year more because you know what is happening with Manchester City.
"I know also that Bayern Munich wanted to get Sancho when he was going to Dortmund, Sancho said no."
