United once again spent big in the summer, with Aaron Wan-Bissaka, Daniel James and Harry Maguire all arriving at Old Trafford.
“Yeah, I think that's been important for a while," Scholes told BBC 5Live when asked if the Reds needed to strengthen.
“They have some talented midfield players in there now. I think (Scott) McTominay has done really well this season.
"And Pogba we all know on his day can be sensational and probably one of the best in the world in that position, but we just need to see it more often, we need to make sure he wants to stay at the club to get that out of him.
“But I think Ole will be looking, he'll be trying. I'd be more worried about the centre-forward position, I know we spoke about Mason Greenwood coming through.
“I always think United, going back to when they were challenging for titles, they had four brilliant centre-forwards and I think that's something that's missing at this minute in time."
