The Daily Mail, as quoted by Metro, is reporting that Manchester United are contemplating a surprise swoop to sign the 21-year-old.
The same article states that the 20-time English champions could bring in Longstaff to help replace out of contract Ander Herrera at Old Trafford.
According to the same story, Longstaff is on Ole Gunnar Solskjaer’s wish list of summer targets as the Manchester United boss looks to revamp his squad.
The Metro report goes on to say that Manchester United have held initial discussions surrounding Longstaff with their Premier League rivals Newcastle.
