Children's sports clubs in Frankfurt

Hi all

I am looking for sports clubs in Frankfurt that cater for 4-6 year olds. Football clubs as a preference, but Karate aswell.

I would need them to run on the weekend though. I have managed to find Karate previously, but this runs during the week unfortunately.

We live in Sachsenhausen and would need to travel by public transport. Also, the kids speak fantastic German, so English speaking would be nice but is not necessary. I am sure that between my crap German and the kids I could communicate

Anyone have any ideas?

Cheers

Dave

I would just like to add that a weekend is not a must if they were to practice around 17.00 or 18.00 If anyone has there children going to weekly ones

My son goes to the International Taekwon-Do Black Belt Center. The kids meet 2 times a week at 16:30 Tue. and Thurs. It is for kids ages 6 and up. They are good and the owner speaks good english. Here is a link. But I am still looking for an activity for my 5 year old daughter if anyone finds something good.
