The Veltins Arena chief is confident that the club will be better than their Ruhr rivals soon, though accepted that Julian Draxler's days are numbered
BVB relinquished their Bundesliga crown to Bayern Munich last season after back-to-back wins in 2010 and 2011 and, despite being praised for reaching the Champions League final, were beaten by the Bavarians on Europe's biggest stage.
Heldt has high hopes that the Gelsenkirchen club - who finished fourth in the BuLi in 2012-13 - will become a better team than their Ruhr rivals soon.
"Dortmund have been ahead of us for a long time now," he told Bild on Sunday. "However, we will overtake them again in the near future."
Schalke have the likes of Julian Draxler and Klaas-Jan Huntelaar to rely upon in the hopes of overtaking Dortmund this season, although Heldt was realistic about the chances of keeping Germany international Draxler in the long term.
"If Draxler keeps on developing at the same pace, we can expect him to leave the club at some point," the Veltins Arena chief admitted.
In addition to their current squad, the Konigsblauen have signed the likes of Adam Szalai from Mainz for a reported €8 million, Leon Goretzka from Bochum and Felipe Santana from Signal Iduna Park.
