Heung-Min Son is looking to improve his game quickly now that he has joined Bayer Leverkusen.
The 21-year old South Korean striker, who scored 12 goals for Hamburg last season, says he is ready to take the next step now he has joined the Lions who will compete in the Champions League after last campaign's third-place finish.
"I want to take the next step to keep improving. Leverkusen are playing in the Champions League, that was a massive incentive for me to make the move," he told Bundesliga.com.
"We are not going to change our system. In Son, we have got a player with all the quality to do the job in that position as well," he said.
"In our first pre-season game together, we started trying to link up and harmonise. These things take time."
And Leverkusen sporting director Rudi Voeller admits the club expect Son to perform after paying 10million for his services.
"We hope he is going to develop a lot further, play even better than he did at Hamburg. We spent a lot of money on him, he's one of Bayer Leverkusen's most expensive ever signings," said Voeller.
