Danny Mills can’t believe Manchester United are trying to sign Newcastle United midfielder Sean Longstaff – when they already have Scott McTominay on their books.

Speaking exclusively to Football Insider, the ex-England international questioned the transfer policy of the 20-times Premier League champions as “slapdash”.

United have already signed 21-year-old winger Daniel James for £15million from Swansea City this summer and are on the verge of landing another 21-year-old in Crystal Palace right-back Aaron Wan-Bissaka.

As reported by Football Insider, manager Ole-Gunnar Solskjaer is pursuing a third, 21-year-old Brit in Longstaff and are ready to offer £18millon to sign him this summer.

“Why are they interested in Longstaff when they have McTominay? It makes no sense,” Mills told Football Insider. “Surely they would be buying like-for-like. Is Longstaff better than McTominay? I’m not sure he is.

“I don’t see what Longstaff would add to Man United. The club’s transfer policy just seems a little bit slapdash. I don’t even understand what their policy is.

“Sure, they’re trying to buy young players with potential. But they already have a decent young central midfielder.”

Longstaff broke into the Newcastle first team last season and made an excellent impression in his 13 senior appearances, including eight consecutive league starts, before a knee injury in March ruled him out for the rest of the campaign.

By contrast, McTominay, who, at 22, is a year older, has played 47 times for United and also been capped on nine occasions by Scotland.
