The midfielder was strongly linked with a move to Old Trafford throughout various parts of the summer transfer window but a switch failed to materialise.
The 21-year-old broke into the Newcastle United first team last season and his fine form seemingly caught the attention of chiefs at Old Trafford.
However, despite the constant speculation, Longstaff ended up staying at St James’ Park as the summer transfer window closed in early August.
The midfielder has gone on to make one assist in four Premier League outings so far this season for Steve Bruce’s men.
And Longstaff has now opened up about how it felt to be linked with a possible move to Manchester United during the summer months.
Longstaff is quoted as saying by the Daily Mail: “You can sometimes get distracted by the outside noise and maybe for a little bit in the summer I was a bit.
“It’s hard not to whenever you go anywhere you see your face on the front of a newspaper and you turn the telly on people are talking about you.
“And it’s not like they’re talking about little things, they’re talking about things that can change your life really.
“The expectation is half what I’ve done and it’s probably a good thing. It does just go to show I did impress people when I got my chance last year.
“So for me it’s about not listening to them and sticking to what I do.”
Meanwhile, Manchester United are aiming to get back to winning ways in the Premier League when they take on Leicester City in front of their home fans on Saturday afternoon.
The Red Devils have taken five points from a possible 12 in their opening four games this term.
