The former France international believes that the structure in German football gives them an edge over the rest of European nations by overcoming their weakness and putting them well-prepared for the future.
In an interview with Kicker, Sagnol said: "Germany will dominate European football over the next 10 years. I think they have no weakness anymore,
"The DFB has a model for football. The structure in Germany is much more stable."
Sagnol did raise one question over Joachim Low's team, however, claiming that the leadership may be a stumbling block.
"Perhaps the only trouble in the German national team is the leadership problem," he asserted. "Germany have not had a difficult phase since 2006, so one cannot say whether the present leadership is good."
Germany have made it to the semi-finals of the last three major tournaments they took part in and are one of the favourites to claim the trophy at Euro 2012.
