"Sources report that van der Garde is assured of a race seat," the newspaper claims.
"Insiders say there is even a small chance that the 29-year-old will get his promotion this year."
Reportedly, that is because Adrian Sutil is behind with his sponsor payments to Sauber, the struggling but pointless-in-2014 team that is "also dissatisfied" with the German driver.
Algemeen Dagblad continued: "The Swiss private team is in desperate need of money. The financial distress is to the point that some employees seem not to have been paid in months.
"It is an open secret that he (van der Garde) has some wealthy sponsors."
Sutil, however, said at Spa last weekend that he has a contract with Sauber for next year, and "I am sure I will be in formula one in 2015".
Van der Garde's management is not commenting publicly at present.
But his manager Jan-Paul ten Hoopen, who is also an executive of van der Garde's main backer McGregor, said in Hungary: "We would like to continue with Sauber.
"We are doing everything to ensure that Giedo can drive."
Meanwhile, after Andre Lotterer's surprise Belgian GP debut, it seems likely that neither the reigning Le Mans winner or Kamui Kobayashi will be in the Caterham next weekend at Monza.
"As a driver," Japanese Kobayashi told Speed Week, "I do not understand or accept the decision. But I do have some understanding of the situation of the team."
Caterham said Kobayashi remains part of the team for now, but Kobayashi commented: "We are talking, but there is still nothing certain yet.
"The decisions are not in my hands."
Specialist Spanish reports claim the two leading candidates to drive Kobayashi's car at Monza are the Red Bull-backed Carlos Sainz jr, who is tipped for Red Bull and Caterham talks this week, and fellow Spaniard Roberto Merhi.
