Robbie Savage says that Manchester United still haven't replaced Paul Scholes, despite their influx of summer additions.
The BBC pundit believes that United have struggled in Scholes' absence over the last two season and that it will be very hard for them ever to find a replacement for him.
He has compared the situation to the one currently facing Liverpool, with Steven Gerrard out of form and needing to be used sparingly.
"Gerrard still has a lot to offer but Rodgers has to decide how and when to replace him - and that will start by leaving him out of some games," Savage said in his BBC Sport column.
"It is similar to the problem United had replacing Paul Scholes - something they are still yet to do."
Scholes retired in the same season that Sir Alex Ferguson did, back in 2013, and although the slump in United's form has generally been attributed to the manager's departure the loss of their key figure in central midfield has certainly had a negative impact.
United struggled to a seventh placed finish last season and there has been little improvement in their game since Louis Van Gaal arrived this summer.
One of their major problems has been in the central-midfield positions, but many felt that they had rectified this problem with their summer transfers.
However, Savage does not go along with this belief and it may leave some questioning whether the likes of Ander Herrera and Daley Blind will be able to follow in their predecessor's footsteps.
Scholes leaves a huge legacy behind him and he will be forever remembered as one of the all-time greats but, given United spent a combined £46 on the two players to replace him, there will be an expectation that they can fill the void left.
So far Herrera and Blind have made impressive starts to their careers at Old Trafford and they will be aiming to continue this form for the rest of the season.
The more prominent problem, currently, remains with United's defence and until their struggles to keep goals out end it looks like their slide will continue.
