The Frenchman says the new boss is testing different formations at the Allianz Arena as the Bavarians step up preparations for the new season
The Bavarians are currently in Trentino preparing for their first season under their new coach and the 30-year-old says the Spaniard is trying out new systems.
"The 4-1-4-1 system is weird," he told Bild.
"It's new, it's completely different. We need to train, talk and learn to perfect it.
"It's normal that the coach wants to try things."
Bayern kick off their Bundesliga season with a home clash with Borussia Monchengladbach on August 9.
