Cola giant, Coca-Cola has admitted its marketing efforts in two of its key markets have failed.

A report by UK paper The Guardian claims that Coca-Cola now has aggressive marketing plans after president and chief operating officer, Jack Stahl admitted the company was disappointed with its marketing efforts in the US and Germany.

Sales in the US and Germany have been flat over the fourth quarter and Coca-Cola, which spends £80m a year on global advertising, has been struggling to re-organise its marketing and advertising arrangements over the past 12 months.
