Paul Scholes believes Liverpool's lack of pace could be their undoing against Manchester United.
The Reds are coming off the back of a depressing Champions League exit in midweek, and the former Red Devil believes Brendan Rodgers' side are ripe for the picking.
He picked out two players in particular who have showed a weakness, which he feels can be exploited.
He told The Evening Standard: "Sterling aside, there was a real lack of pace in this Liverpool team. Both Glen Johnson and Jose Enrique struggled and you would expect that, on Sunday, United will attack the space between Johnson and Martin Skrtel where Basel got so much joy."
While a slight on both defenders, it is as much about the way they play in tandem, and how they do not compliment each other effectively.
How this pans out could depends on whether Angel di Maria is fit to play for Manchester United, who adds a different dimension for the Red Devils, but the space is also one in which either Robin van Persie or Wayne Rooney could effectively drift into.
Rodgers may elect to change his team, and play Javier Manquillo at right-back to freshen up his options, and attempt to negate the poor Johnson-Skrtel axis on the right which Scholes refers to.
