Oliver Kahn has lashed out at Matthias Sammer's handling of Bayern Munich, claiming the official's involvement in day-to-day club activities border on intrusive.
The retired Germany goalkeeper feels his former international team-mate, who was named the new technical director of the Bavarian giants in July, has to take a necessary step backwards in order to avoid interference with coach Jupp Heynckes.
"With Sammer constantly being at team training sessions as well as his very public comments on Bayern Munich's game plans, he appears to be like a second coach," lambasted the 43-year-old in his personal Bild column.
"Meddling in the coach's department poses potential conflicts at organisational level that will quickly lead to failure on the field.
"Club operations only work successfully if task distribution is clearly defined and respected by all parties."
Despite this perceived conflict of interests at management level, Bayern have embarked on a strong start to the season, ousting traditional rivals Borussia Dortmund in the DFL-Supercup before sweeping to a 3-0 Bundesliga opening-day victory over Greuther Furth.
