Following the draw on Monday morning, Bayern Munich defender Mats Hummels was quick to send a message out to his former boss, under whom he won two league titles in Germany
Hummels and Jurgen Klopp were on the same side in the 2013 Champions League final, but in two months time they will go head to head as Bayern Munich face Liverpool in the last 16 of this year's edition.
Clearly excited by the prospect of doing battle with his old colleague, Hummels simply tweeted: "I [see] you my former coach."
Since leaving Borussia Dortmund, Hummels has won back-to-back league titles with Bayern Munich, but is yet to play in a Champions League final in his new colours.
