Newcastle United hero Malcolm Macdonald has urged Sean Longstaff to resist a move to Manchester United.

Supermac wrote for the Evening Chronicle: "If I could offer a piece of advice to Sean Longstaff it would be to stay at Newcastle United, and establish yourself at St James' Park.

"He started to really impress people but what he has to do now is scare people with what he is capable of achieving - that is what I set out to do at Newcastle in my first season, scare people.

"I arrived at Newcastle from Luton in 1971, aged 21.

"My old manager at Luton, Alec Stock, he was a bit of a mentor and said to me 'what you've got to do now is plant yourself in people's minds because when you're doing it in the penalty area, you're also doing it in people's heads'.

"And that is what Sean Longstaff got to do. If a move came along now, it would be the wrong time."
