Sean Longstaff will become a Manchester United player before the end of the transfer window, according to ESPN journalist Mark Ogden via The Express.

It is said that Manchester United and Newcastle United have different values of the midfielder. The Red Devils are said to value Longstaff at £30m, while the Geordies value him at £50m.

Ogden says he doesn't believe any club will pay £50m for Longstaff, but he does think a move to Old Trafford will happen before the end of the transfer window.

"I think they’ll still keep plugging away at that one," Ogden said on the Transfer Talk podcast (via The Express). "Newcastle have shown that they’ve got a few problems at the moment with the ownership, the manager change. Sean Longstaff is a player that has got potential.

"He’s a Newcastle lad so it will be hard for Newcastle to let him go. But I think Newcastle tend to sell when the price is right.

"I think at the moment we’re just seeing negotiation tactics. Newcastle are holding out for £50m - they won’t get that, nobody will pay that for Sean Longstaff."

The links between Longstaff and Manchester United could be due to the departure of midfielder Ander Herrera, who left for Paris Saint Germain. As well as the exit of Herrera, Manchester United may need to bring in another midfielder, after rumours surrounding a potential departure for Paul Pogba.

Any move for Longstaff will be very naive from Manchester United. Longstaff has only played nine Premier League games in his whole career at Newcastle United. He has yet to be tested severely in his short Premier League career, and bidding upwards of £30m, which is the reported value Manchester United have placed on him, would be unjustified.

After the exit of Ander Herrera, Manchester United have the chance to blood more youth rather than continue to fork out, which has rarely worked out of late, as highlighted by The Sun last year. Solskjaer himself has been heavily praising both Scott McTominay and Andreas Pereira, players who he says can replace Herrera.

Sean Longstaff may go on to have a long and fruitful Premier League career, however, as of right now, there is little justification for spending potentially big money on him.
