Fabinho admits Liverpool must "try something different" after their recent dip in form.
The Reds have drawn their last two games, including last night against West Ham United.
Manchester City can supplant them at the top of the table on Wednesday, and Fabinho says something needs to change at Anfield.
The versatile Brazilian told ESPN: "We have confidence.
"We enjoyed a brilliant December, which was almost perfect, but now we have had this dip.
"It is difficult to explain why this has happened. I believe that now teams who play against us sit very deep. We need to do things a little differently and maybe we aren't doing this - we are unable to find the spaces.
"Often, we want to go through the middle and it is difficult against physically strong and defensive teams. We need to find solutions and in these past few games we haven't."
