Robben experienced five coaches in his time with Bayern. At the SPORT BILD Award 2019, he revealed who is the best one.
"Of course that's difficult, I've seen many beautiful things with many coaches and we've been very successful. But if you ask me who was the best, I say Pep Guardiola. I enjoyed it most with him, he is just awesome, "said Robben.
"When Guardiola coached Bayern, I was already 30 years old. At that time, I was just trying to come up with stable performance and not to regress. But under Guardiola's coaching, I became better. I quickly kicked a lot of places I had never thought of before. He is the best."
