Liverpool pair Jurgen Klopp and Loris Karius were back with Mainz on Saturday.

The Liverpool Echo says Klopp used his weekend off to return home to Germany to manage in a testimonial game at Mainz, where he faced off against another former Borussia Dortmund coach in Thomas Tuchel.

Tuchel followed a similar path to Klopp and was at Mainz for five years before a two-year stint with Dortmund in the Bundesliga.

Karius was also in action as he returned to his former club to play his part.
