Since the 1994/95 season, the final year before the Bosman ruling, the number of foreigners plying their trade in the Bundesliga has almost trebled, jumping from 21.1 percent to 60 percent at the start of the 2003/04 campaign.

"It can not continue," stated Mayer-Vorfelder. "The percentage of foreigners in the Bundesliga is close to 60 percent meaning German talent is unable to break through.

"This is of course counter productive for the German national team."

Beckenbauer, known as the 'Kaiser', believes Germany should follow the example of Italy where Serie A and Serie B clubs can only recruit one non-European player per season.

"Italy already has a restriction on non-Europeans and that would certainly be a good step for us," he said.

Kaiserslautern currently have players of 17 different nationalities in their squad while Borussia Dortmund have six Brazilians on their books.
