The former Germany defender is not convinced the Brazilian centre-back is good enough to make it at the highest level
The former Roten, Juventus and Borussia Dortmund defender feels the Brazilian is a decent player, but stressed that he remains unproven at the highest level.
"I find Bayern's situation in defence very interesting, the two centre-back positions in particular," Kohler wrote in his column for TZ.
"This is not their best area in my opinion. Dante is certainly not a bad player, but Bayern are aiming high in Europe, and it remains to be seen whether he has the quality to succeed at the highest level."
The 28-year-old defender featured for the full 90 minutes in Bayern's opening two Bundesliga games.
