Liverpool manager Jurgen Klopp has claimed that he is yet to decide on who to play up front against Borussia Dortmund tomorrow night, with Daniel Sturridge and Divock Origi both in good form.

Origi was preferred to Sturridge in last week's Europa League quarter-final first leg in Germany, and the Belgian scored in a 1-1 draw at Westfalenstadion.

Sturridge scored in last Sunday's 4-1 triumph over Stoke City after being given the nod to start, and he impressed alongside Origi when the forward was brought off the substitutes' bench.

"We have a few different possibilities to find a lineup," the Liverpool Echo quotes Klopp as saying. "There is no final decision yet. Maybe we should have all the goalscorers for Liverpool FC on the pitch and let's hope Dortmund don't recognise it!

"We have to wait for the last information before we make a lineup. It's not about how many strikers we have on the pitch to score goals. There are always difficult decisions to be made. Every player I could bring into the line up is in good shape.

"This is more a moment where you cannot make any mistakes as manager. It's not a problem for me. It's only difficult for players to accept in this moment they are not in the line up or in the squad. It's not that I don't know who to bring into the game."

Liverpool can progress into the semi-finals of the Europa League with a goalless draw tomorrow night due to the away goal scored in Germany.
