Podolski slams bosses at relegated Cologne

German international Lukas Podolski on Thursday slammed the management at relegated Bundesliga club Cologne ahead of his departure for English side Arsenal. "In three years I've known five coaches. Not easy to succeed in these conditions," said Podolski in an interview with the daily Bild. The 26-year-old took the examples of clubs such as "Mainz, Hanover and Dortmund, who made good decisions for this post", supporting coaches and "not saying much during difficult times". Cologne were beaten 4-1 by Bayern Munich last Saturday and finish in 17th position, ensuring relegation for the fifth time in the last 15 years. But Podolski, who has won 95 caps for Germany, does not regret his return in 2009 to the club where he started his career, after a fruitless three seasons at Bayern Munich. "Returning wasn't a mistake. I'm more experienced, more mature," said Podolski, who finished the season with 18 goals and was joint-fourth in the scorers' chart. He said he was moving to Arsenal "to win titles" in a deal worth an estimated 13 million euros.
