Lukas Podolski is considering his future at FC Cologne.
The Germany striker is being tracked by Arsenal and Tottenham.
"I was told the plan was to get back into Europe here, but we have failed and of course I have to ask myself why," he said.
"Whenever I am with the national team, I always notice people shaking their heads when yet another story emerges from Cologne which has nothing to do with sport.
"My family and friends may live here and I know every corner of the city, but if I am in top condition, then I think I could fit into any side in Europe.
"I am not forced to stay only in Cologne."
