Liverpool boss Jurgen Klopp is looking forward to their friendly at former club Mainz 05.
Klopp kicked off his management career at Mainz.
He told liverpoolfc.com: "I love my memories around Mainz of course and I have still a lot of friends there but that's not too important. I think I spoke a few times about it and it was special for Zeljko [Buvac] and myself, a very special time as we both played there and then became manager and coach.
"It was a great time and we learned everything. What we learned - especially myself and what I know today - we learned there because we had to because no-one else could do it, so we had to start ourselves without other people watching what we were doing so that's our way.
"We have still a lot of friends there but when we come back it's not a time to meet friends again. It's like when we played Borussia Dortmund [in the Europa League last season] even when it's only a friendly game or whatever then it's not a time for me to be too private. I'm not able to do this unfortunately so it's an important game and that's why we are there."
