United are reportedly closing in on a big-money move for Sancho, who was heavily linked with the Red Devils last summer.
Borussia Dortmund rejected an opening bid of £67m for the 21-year-old English winger earlier this month.
However, United have reportedly improved their offer and put together a stunning £77.5m deal to land Ole Gunnar Solskjaer's top target.
And it initially appeared that Rashford confirmed Sancho's forthcoming arrival at Old Trafford via a tweet to a supporter.
One fan simply posted, "Announce Sancho Marcus," which included eyes emoji in the tweet.
United fans on the social media platform were stunned when Rashford's Twitter account responded with a "yes x" reply on Tuesday.
The tweet has since been removed from Rashford's account, but the United star has since confirmed it was a "little hack" and now he is back.
The 23-year-old tweeted to his 4.5m followers: "A little hack and I'm back. Morning all."
Sancho was in superb form for Dortmund last season as he scored an impressive 16 times and registered 20 assists in 38 appearances.
The England international, whose current Dortmund deal expires in 2023, has already agreed personal terms with United ahead of his potential move.
United boss Solskjaer is keen to bolster his attacking options ahead of the new Premier League season.
Sancho is currently on international duty with England at Euro 2020, but the United target's playing time has been limited under Gareth Southgate.
The Dortmund star was left out of the England squad for his side's opening Euro 2020 clash against Croatia.
Sancho was on the bench for the 0-0 draw against Scotland and only made a brief cameo in England's 1-0 win over the Czech Republic.
The England winger was an unused substitute in England's sensational 2-0 win over Germany in the last 16, but Erling Haaland showed his support for his Dortmund teammate on Twitter.
Bayern Munich legend Lothar Matthaus admitted that Sancho's lack of England playing time has "surprised many in Germany."
