Liverpool are one of the greats in Europe, and being able to be part of the history of such a great club is gratifying to me.
Klopp is a fantastic guy. I rate him as an extremely professional coach, perfectionist, and a winning mentality.
Everyone hears stories about what it means to be a Liverpool player, but, until you live it personally, you cannot really understand it.
I like to relax; of course I do! But when I am inside the pitch, that is it. You have to go on full on from the first minute.
I started out as a defender. I played as a full-back, and then I moved into the centre. I played defence right the way through until the Under-18s. Honestly!
It comes easy to me to run. I picked a lot of it up from Germany. I had four-and-a-half years there, and I learned you have to be on the automatic button. Press it, and you go: you keep running, chasing and working.
I've always been shy; it's just that I transform on the pitch. I'm a different person. Off the pitch, I'm another person. That's how it has to be.
I remember the first day getting to Hoffenheim. Minus 20! The weather was different; the food was different. It was cold, and I found it difficult, but I am not someone who gives up.
