Sports director Christian Heidel of FSV Mainz 05 does not see RB Leipzig as a big club despite their current highs in the Bundesliga. "They are doing a good job but are still a long, long way from being a big club," said Heidel after Mainz 05's 2-0 defeat at home to RB. This can be seen, for example, in the fact that only 600 fans came to Mainz despite Leipzig's strong Bundesliga season so far.
"That has to grow and that takes 50 years. It takes generations. It's not the club's fault," explained Heidel. But RB Leipzig will not be one of the big clubs as we know them for that long.
