Inside the players' tunnel.
Players from both sides stood in two lines.
On Dortmund's side, standing at the front was captain Kyle, who is also a member of the German national team and is known for his aggressive and ferocious tackles.
Standing side by side with him was Leverkusen's captain and once the soul of the German national team, Ballack.
Kyle and Barack go way back as far as the national team level is concerned.
Barack is now 35 and Kyle is now 32.
As their age rose, both began to decline to varying degrees, and both are now away from the national team.
Being able to meet in the league also makes these two sigh with relief.
Kyle offered a hug to Barack and then said, "Big brother, I honestly thought you were going to retire, but I didn't think you'd make another appearance!"
Barack said with a slight smile, "Sure, I'm getting older, but my heart isn't dead yet!"
