I'm so happy that I was able to make it to 120 games for Germany; 175 games would have been possible. I've had many great moments, but particularly the way the fans supported me and the road to the final in Rio.

The small teams are playing well. That's visible, and it has had an impact on German football.

I will travel a lot after my career.

I had a lot of pressure in my career: when you play at World Cup or Champions League final, there is pressure on your shoulders.

After snowboarding a fair bit in 2011 and 2012 to test equipment, I got pretty good at it, and some friends at Adaptive Action Sports talked me into competing at the exhibition event at the Winter X Games in the adaptive boardercross. I was able to step up my game pretty quick and compete. I took last place, but knew I could improve.

It's not an exercise on how to avoid getting hit. I think there are certain safety measures that take care of the mental part of it, with players not looking to hit somebody in the head. They've done that. But let's not take the entertainment value out of football.

They're great memories, not just as a footballer but as a person growing up - it sounds daft, but to come away from Liverpool to play the first-team football I needed. It's a fantastic place, a huge football club and they helped me a lot. I'm grateful for coming through there.

We need to wake up to idea that you cannot treat sport on equal terms with other parts of the economy.
