But there's a void in their attacking ranks as the current leaders are without ideal cover for their Brazilian No.9. And even though he's been fortunate with injuries, he can't play every single game.
The Reds' interest in Dabbur is serious and sources have told Football Whispers that Barry Hunter, the chief scout for Liverpool, has travelled to Austria on a number of occasions to watch the forward in action.
The Israel international came of age during the 2017/18 campaign as he netted 22 goals in 32 matches. He also chipped in with a further five assists. He added another eight goal involvements in the Europa League as the Austrian club stunned many by reaching the semi-finals.
The 26-year-old already has 16 goals, including three against Celtic, and six assists in all competitions this term and, like a certain Mohamed Salah, he's proving to be more than just a one-season wonder.
Dabbur wouldn't be a like-for-like replacement for Firmino in the starting XI but his all-round game is on par with the Brazilian's even if he is more of a natural forward.
He's creative, versatile, selfless and, perhaps more importantly, he'd be yet another shrewd signing without the Reds having to break the bank despite the striker having two-and-a-half years left on his current deal.
Liverpool don't usually do business in January with Klopp on more than one occasion saying he doesn't feel the winter window offers value for money.
But not only does Dabbur offer that, he'd give the team added depth in attack as they look to continue their title push as well as a tricky tie against Bayern Munich in the Champions League.
