Mainz have shocked the German league with seven straight wins to lead the table with a strong team spirit and their young players like Andre Schuerrle and Lewis Holtby are becoming household stars here.
Likewise, Turkey have won both of their Group A qualifiers so far, are just behind Low's side at the top of the table and with Dutch coach Hiddink in charge, they threaten to upset the hosts in the German capital.
"The Turks are rested, they did not play at the 2010 World Cup and have had more time for preparation. Turkey is like Mainz," Low told German daily Frankfurter Allgemeine Zeitung.
Germany's FIFA World Cup™ stars - particularly those at defending champions Bayern Munich - are struggling for form in the Bundesliga after the national side finished third in South Africa.
"We feel that our players are still below their potential after the World Cup," admitted Low.
Low will be without captain Michael Ballack and playmaker Bastian Schweinsteiger, but says he has a good feeling about the match at Berlin's Olympic Stadium.
