Michael Obafemi held off Lindelof at the far post to turn home a 96th minute equaliser to hand Ralph Hasenhuttl's men a share of the spoils at Old Trafford.
That goal could prove costly when all is said and done at the end of the campaign.
"Lindelof, I think, has to be a stronger there," Scholes told Premier League Productions.
"He has to be goal side. He allows himself to get a little bit bullied by the centre forward as he manages gets a foot in.
"I don't think Lindelof really reads the danger there as he should do as a centre half."
