The Reds have won just two of their seven matches so far this term and they already trail leaders Arsenal by 11 points.
Jurgen Klopp’s side reached the Champions League final last term and pushed Manchester City to the final day of the Premier League season, on top of winning the FA Cup and Carabao Cup.
But the Reds have been lacklustre so far this season and they’ve been a poor resemblance of the side that Klopp has built.
Saturday’s 3-3 draw against Brighton summed up Liverpool’s campaign so far, with the Reds giving away a two-goal lead, showing good spirit to fight back but then squandering their advantage in the final stages.
And Wenger believes that the loss of Sadio Mane, the failure of Darwin Nunez to settle and the side being ‘less effective’ at recovering possession has seen them drop-off this season.
‘It’s difficult to understand,’ Wenger told beIN Sport.
‘They have the same core and the same type of playing style. But they are less effective at getting the ball back than before.
‘Nunez, at the moment, hasn’t played much for them yet, and they’ve made a big investment. He is sitting on the bench.
‘They lost Mané, who was a top player in big games. He had something, an aggressive attitude and determination.
‘He would score no matter what, he would make things happen. It’s hard to measure what it takes away from them. They are missing something they had before.’
The Reds take on Rangers tonight as they look to bounce back from a 4-1 defeat to Napoli last time out.
Nunez could start, having missed out on a starting spot against Brighton on the weekend.
