Aldridge was particularly impressed with Origi's performance against Southampton last week, and described Daniel Sturridge as a 'class act'.
Origi scored his first goals for the Reds with a hat-trick in the 6-1 win over Southampton in the League Cup, and it has led to Aldridge getting excited about the forward options at Jurgen Klopp's disposal.
He wrote in his Liverpool Echo column: "It was a great display and the thing that stood out was the fact we saw Divock Origi at his best.
"It really was a stunning hat-trick and display overall.
"There’s much more to come from him because he’s only young but that was great to see.
"As for Daniel Sturridge, well he’s just a class act.
"The manager has four really good options at the front if Daniel Sturridge stays fit, though that’s the big question of course."
Last week's 6-1 win over Southampton seems a little longer ago for the Reds following their humbling 2-0 defeat at the hands of Newcastle United, but it showed that there are options for the side, even with one striker sidelined in Danny Ings.
There is, of course, Daniel Sturridge to consider whenever Liverpool's strikers are brought up - he has to be in the conversation at some point, and so does his fitness. He has shown why he is valued so much within the side, because he can be a deadly finisher, but the question marks over his fitness are never far away. Having made three consecutive appearances, it seems that he is working his way back to full fitness.
Origi's performance has certainly put pressure on the senior strikers to perform, and though he only came off the bench against Newcastle and didn't have the time he would've liked to make an impact, he still looked busy. The Magpies were wary of his threat, and more performances like that will certainly have Sturridge and Christian Benteke looking over their shoulders.
Jurgen Klopp has already shown that he likes to keep his side fresh during busy periods of fixtures, so there could be more opportunities for Origi to impress. It looks like all of the strikers could be on their toes in the coming weeks.
