Former Liverpool defender Dejan Lovren has questioned whether they can snap their early season slump.
The Reds have endured a lacklustre start to the new campaign, with just two wins in six games leaving them nine points behind Arsenal at the top and eight behind Manchester City and Tottenham.
Zenit defender Lovren told Sportske: "I talk to Salah at least once a month.
“We will see how the story with Liverpool will unfold, whether they are just in a bad period or if the story will go down. They have to go back to the Liverpool they used to be.
“The Premiership is a very tough league. Some new players came to Liverpool, they need to adapt."
