Before packing his bags for Bavaria, Díaz sought out advice from Liverpool's new record signing Florian Wirtz, who knows German football inside out after coming through the ranks at Bayer Leverkusen.
"I already had some knowledge of the Bundesliga," he said. "I love watching football and all the competitions. I had the opportunity to talk to Florian in Liverpool, and I know it's a physical league. I hope to have a great debut. I've been here at the club for about two weeks, and I need time to settle in."
