Gary Neville believes that Liverpool are struggling because they are not playing with the same intensity as last season.
The Reds fell to their sixth defeat of the campaign in the Premier League as they were beaten 3-1 by Crystal Palace at Selhurst Park, and Neville is adamant that Brendan Rodgers's side's troubles are not all down to the departure of Luis Suarez.
Neville told Sky Sports News: "Structurally Liverpool aren't a great defensive unit but what they were great at last season was springing into attack and reacting quicker to win the ball back.
"That's not to do with quality, it's not to do with Luis Suarez or world class players. It's to do with the mentality, fitness and confidence. The difference is night and day. If you look at Crystal Palace in the game, they look like the ones in fast forward and Liverpool are in rewind.
"They say in football that your hard work results in performances, results and goals. If you said to me what Liverpool's faults are at the moment, I'd say it's in attack. But, actually the reason they're not getting the level of attack is because they're not getting the ball back quickly enough, at the same intensity."
Liverpool are 12th in the Premier League with 14 points from their 12 matches this season.
