Aldridge wouldn't be surprised to see both Origi and Sturridge starting, but admits the Belgian is favourite to lead the line.
Former Liverpool striker John Aldridge has said the second leg of this week's Europa League quarter-final tie with Borussia Dortmund could require a different approach from the Reds compared to the game a week earlier.
The first leg in Dortmund finished 1-1 with Mats Hummels cancelling out Divock Origi's first half strike, but the Reds hold that crucial away goal.
Origi started ahead of Daniel Sturridge in Germany and impressed, and after coming off the bench to score twice on Sunday in a 4-1 win over Stoke City he could be asked to lead the line again - but Aldridge feels there is a possibility of both the Belgian and Sturridge starting the game together as he urges the side not to play for a 0-0 at Anfield.
He wrote in his Liverpool Echo column: "Origi is favourite to start, you imagine, after being 'rested' with this game in mind. But then, Daniel Sturridge was sharp on Sunday and he's a different proposition at Anfield.
"This will be a different game to the one last week, and it might require a different approach.
"Maybe Klopp plays Origi and Sturridge up front. I wouldn't be overly surprised by that, either.
"One thing Liverpool cannot do is sit back. Not a chance. Klopp has to set us up to win the game, there's no way he can play for a 0-0 draw, even if it sends us through."
Playing with two up front could leave the Reds a little too open, but the goal threat that both Origi and Sturridge can carry could be significant, and if Liverpool were to get a fast start they could feasibly put the game out of reach from their opponents. One of them can easily drop back into midfield at times to maintain a solid shape, while both players have the pace that can trouble a Dortmund back line.
However, no one should be under any illusions that Liverpool still face a huge task to make it through to the last four - even if they have the slenderest of advantages.
Dortmund still possess a significant goal threat and it would be some effort from Liverpool to keep a clean sheet. It is going to be fascinating to see just how Jurgen Klopp will want his side to approach the encounter.
