From Firmino and Salah to Origi and Shaqiri - 42 goals to 10

So far this season, Roberto Firmino has scored 16 goals, and Mo Salah himself has managed 26. This means between them they have now found the net 42 times this campaign - a figure that makes them a rather deadly duo.

However, they are also a duo that will not be available for Barcelona's visit to Anfield on Tuesday night. In their place, Klopp has selected Divock Origi and Xherdan Shaqiri, who between them have less goals than Firmino or Salah individually.

The Belgian striker has scored just 4 goals this season, whereas the Swiss midfielder has fared slightly better with 6 strikes. 

However, Origi does come into the game off the back of a winning goal against Newcastle on Saturday that kept his side in the title race after scoring a header assisted by the aforementioned Shaqiri - maybe there is hope for Liverpool...
