The Argentine has reiterated his belief that the biggest difference between his side and the European champions is economic.
Both sides have spent over 100 million euros this summer. While the Spanish champions recruited a slew of players, including Antoine Griezmann and Mario Mandzukic, only James Rodriguez, Toni Kroos and Keylor Navas arrived at the Bernabeu.
"We've got seven or eight players with 95 million euros, they bought two with 95 million euros," Simeone told the press before the two teams' Supercopa clash Tuesday. "There's a little difference. But the club has always had this creativity. We are forming the group, but the group is not just 11 players but 18 or 20."

Simeone went on to say that his side would cope without Diego Costa, who joined Chelsea this summer after leading Atleti to La Liga's crown.
"The team structure will not change. The intent and agression will be the same because it comes from the core. That gives us the stability to keep going with the same idea," he said. "Mandzukic's characteristics are not the same. Raul Jimenez is the closest thing to Costa without being Costa."
Atleti lost the Supercopa last season to Barcelona on away goals and Simeone is keen to make amends this time out.
"[The Supercopa] is more about money than it is real — it's two games at the start of the season that television pays for. A final is a final, not two finals," Simeone said. "Last year we were close. Now we have to make a major effort."
