New signing Donny van de Beek opened his account for the Red Devils on the day, but the Dutchman remains United's only acquisition of the summer despite a protracted transfer saga surrounding Jadon Sancho.
Neville believes that the club must act swifter than they have done in the market so far, telling Sky Sports News: "That first half won't have settled down the Man United fans who have been demanding more activity in the transfer market.
"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."
