VfB Stuttgart caretaker coach Jürgen Kramny has revealed he received a 'good luck' message from Liverpool boss Jurgen Klopp.

The pair worked together at Mainz before Klopp left for Borussia Dortmund.

"Jürgen Klopp has wished me good luck for the match in Dortmund," revealed Kramny.

"We have always remained in touch since our time with Mainz."

Kramny was named VfB interim coach this week.
