With Arsenal still keen, the pair clashed on the weekend.
Draxler played down a spat with Keller during the weekend's win over Hertha Berlin.
"We had contrasting views on a certain situation and had a discussion. We came to the conclusion that I was right [laughs]. No, we had a misunderstanding, but it was nothing serious."
Keller added: "It was about running paths...we discussed it and Julian was right. Empowered players are no problem for me. "
