Real Madrid will reportedly have to end their interest in one of Kylian Mbappe or Erling Braut Haaland next summer.
Los Blancos have long been linked with both players as they consider potential long-term replacements for Karim Benzema.
However, according to Sport, the financial implications of the coronavirus pandemic will again limit Real's spending in the transfer market in 2021.
The report claims that president Florentino Perez will be unable to add both stars to Zinedine Zidane's first-team squad.
Mbappe, who will cost significantly more than Haaland, has less than two years remaining on his contract at Paris Saint-Germain, a factor which will be taken into consideration by Real.
Meanwhile, Haaland possesses a release clause in his contract at the Westfalenstadion, which will likely be activated by a number of clubs at the earliest opportunity.
