Bayern is a global player,” Hoeness told a digital trade fair in Cologne. (Dortmund) will never, never, never catch up to our enormous success over the last 30 years. They will have to win the German title ten times in a row to perhaps be more popular.”While Bayern have won away at Greuther Fuerth and trounced Stuttgart in Munich in their opening games, Dortmund opened their bid for a third consecutive league crown with a narrow win over Bremen and a draw at Nuremberg.Both Bayern and Dortmund have UEFA Champions League games looming with Munich hosting Valencia on Wednesday while Borussia are at home to Ajax on Tuesday and Bavarian coach Jupp Heynckes has said he will rotate his squad.
