soccer player around? (Karlsruhe)

Hi,
I am quite new in Karlsruhe and i am looking for people who want to play football on regular basis.

In italy i used this website Protected content but in germany is not that popular.

I think it is a nice tool to organize the matches...

Protected content

looking forward to your feedback and suggestion, maybe you know a better website

Regards
