Patrik Schick, a striker for the Czech Republic, enjoyed his success after moving from Euro 2020 to Leverkusen, where he has six goals in seven Bundesliga games this season.
"Everything is going according to plan," Schick said, with Leverkusen in second place in the Bundesliga, one goal behind Bayern Munich.
Schick is the leading scorer in the Bundesliga, trailing only Dortmund's Erling Haaland and Bayern Munich's Robert Lewandowski, who have each scored seven goals so far.
"Everything started at the European Championships where I scored five goals, I took this form also to the Bundesliga and I never stopped working hard," Schick told reporters.
"We have a new coach who gave the team a new face, we play attractive attacking football -- I think we have the players for that at Leverkusen," Schick said.
"Against last season, we play much more as a team, and the mood in the locker room is much better too, which also has an impact on the pitch," he added.
"I'm glad I can score like this early into the season, that's always important for every striker, but on the other hand we have only played seven games so far."
