Bayern either wanted Gotze's talents to help their style or they decided to take the soul from their rivals. Evidently they did both. Yet it's incredible that Gotze chose to abandon his coach, mentor, club and home. He chose their rivals, which was a bitter pill to swallow.
Perhaps Klopp is guilty of pushing his stars into the arms of Bayern and their new coach Pep Guardiola. As Dortmund were on their rise Klopp would use footage of Barca and show how united and passionate they were. He used Barca's unity as a model for his team.
“[They celebrate each goal] like it's the first they've ever scored. It's the perfect thing to show my team,” Klopp reflected this week. “I do it very often. I show them photographs of how Barcelona celebrate."
It worked. Yet one imagines that those players looked at Barca and thought, "wow, I would love to work with Guardiola" and that is what happened with Gotze (and Lewandowski). Klopp inadvertently pushed his stars into the arms of his rivals.
