United flattered to deceive once again on Saturday as they let a first half lead slip to draw 1-1 with Southampton in the Premier League at Old Trafford.
The Red Devils have now taken the lead in each of their last three games across all competitions but have failed to emerge victorious.
Rangnick’s side are still stuck outside the top four places amid a poor run of form.
The German tactician has been placed in temporary charge until the end of the season following Ole Gunnar Solskjaer’s dismissal late last year but his methods have left Scholes unconvinced so far.
"That's the feeling around the place [quiet inside Old Trafford] there's a lack of interest now with how the season's been," Scholes said in his role as a pundit on BT Sport.
"It's been a bad seven days, it's really been a bad six or seven months.
"The sacking of Ole was coming, we all knew that, but where was the plan? There has to be a plan, there has to be an elite, top coach into the football club to revive the football club.
"It's Manchester United, they should have the best of everything, and to not have a plan and bring what is a sporting director... he's coached a team two years out of the last 10.
"Don't get me wrong, I like the man, he comes across well, but he's looked like he's lacked coaching in the last five or six years. They're a team of individuals, you look at the difference today in United to Southampton.
"Southampton were brilliant, the coaching, methods, passages of play, it was fantastic.
"One team have got a proper coach, the other team has a sporting director, which isn't right for Manchester United."
