Earlier in the evening, Neville had picked out three areas of the first-team squad where he believes United need to improve before October 5.
“That first-half won’t have settled down the Man United fans who have been demanding more activity in the transfer market,” he said.
“It’s not happened yet. The club just don’t seem able to get things done quickly enough or efficiently enough.”
“They need a centre-back, they need a left-back and they need a forward-striker.
“Without them, Man United are not going to close the gap. Chelsea have acted and Liverpool are acting – they are already stronger.”
United have been in negotiations to bring in Sancho but have yet to broker an agreement with Dortmund entering the final fortnight of the window.
They opted against going for new Tottenham signing Sergio Reguilon due to Real Madrid’s insistence on a buy-back clause while did not have serious interest in Gareth Bale, who has joined Spurs on a season-long loan.

The Red Devils have not made a move for centre-backs Kalidou Koulibaly or Dayot Upamecano of Napoli or RB Leipzig, either, despite incessant links.
Pre-match, fellow United legend Patrice Evra was also critical of their lack of business this summer.
“As the people know I’m always behind United but I’m disappointed,” he said.
