Speaking on the exorbitant transfer fee paid for Wirtz's services, Muller told CBS: "What's 150 million? It's unreal. It's just a number between clubs. Who can feel what 150 million means? You can't get Neymar (who moved from Barca to PSG for €222m in 2017), but you can plant many trees with that."
However, Muller has no doubt that Wirtz will quickly settle in at the English champions, adding: "Florian fits in everywhere. He's not only a very good footballer, but also mentally very strong. At the end of the day, we're used to dealing with [big transfer fees]. The expectations are so high anyway."
