Former Borussia Dortmund defender Christoph Metzelder believes that Jurgen Klopp deserves most of the credit for the club's success in recent years.
The 46-year-old has led BVB to two Bundesliga titles and one Champions League final in his five years in charge of the club, who were almost bankrupt fewer than 10 years ago.
And Metzelder feels that the former Mainz boss is behind their recent revolution at Signal Iduna Park and that their success has allowed them to grow.
"Borussia Dortmund have acquired in recent years, through the world of Jurgen Klopp, a style of play that is extremely dominant," he told Goal.
"Due to their recent success and the additional revenue, they have put together a quality squad, now also with depth."
Another of the former Germany international's old clubs, Schalke, were expected to challenge for the Bundesliga, but Metzelder says Dortmund and Bayern Munich are already out of sight.
He continued: "Bayern Munich and Dortmund seem to be gone. I believe Schalke, Bayer Leverkusen, Borussia Monchengladbach and Wolfsburg will fight it out for third and fourth.
"They have lost ground after a stumbling start, but I believe that they can reach fourth this season, they will continue to stabilise."
S04 are now sixth in the Bundesliga and Metzelder believes that injuries have prevented them from reaching a better position in the table, along with strife within the club.
"With important players like Jefferson Farfan and Klaas-Jan Huntelaar missing, you feel it immediately. The lack of stability can also be attributed to the unrest and upheaval with the coaching position, too."
Julian Draxler has been quieter than usual for Schalke in recent matches but Metzelder is confident that the 20-year-old will soon be back on top form.
"It's part of an athlete's life," he explained. "Even the greatest players have not won every game and put in great performances. It is a normal process and the expectations on Julian are extremely high of course.
"As a young professional, you're exposed to many temptations. He has found his own way to develop his skill and talent steadily."
Schalke face Werder Bremen at the Veltins Arena this weekend.
