Liverpool striker Divock Origi has said he has learned from watching teammate Daniel Sturridge closely in training.
Origi scored a vital away goal in the first leg of the Europa League quarterfinal in Dortmund last week and is vying with Sturridge for the chance to lead the line in Thursday's return at Anfield with the tie poised at 1-1.
He capped a fine week with two goals against Stoke as a substitute on Sunday and hailed the influence of Sturridge, saying: "He's a big player, so when I play with him I see a lot of things I can bring out in my game.
"I try to see how Daniel moves. He moves very smartly, he comes between the lines and he finishes very well.
"He is creative, so he has a lot of qualities and talent. That's my aim -- to make the same progress as him.
"My qualities are more when I move around and use my speed. You have to learn how to use this. I have seen big improvements."
Origi has made big strides since been named in Ligue 1's worst XI during his season-long loan spell back at former club Lille, a condition of his £10 million transfer in summer 2014.
"It was an awful year," he said. "I'm sure it made me a lot stronger. The football world can build you up and you can sometimes go down, but when you have a good base you don't have to worry."
Origi has worked significantly on his physical strength and explained: "When you come to the Premier League, you realise you have to be physically strong because it is a very intensive league.
"I came here and saw how professional all the players were. Seeing how the big players worked inspired me."
