Klaus tbh I think Wirtz already did bits in his career, an unprecedented unbeaten double plus EL final run is worth raising on your CV. Doing it as your teams best player aged 20 with 40 g/a+ is noteworthy too.
You might have a point about him being physically soft fwiw he's never had to fight off animals like the roided orcs playing in England, he got a bit more protection from refs in Germany and also his style of play - beating a defender with smart movement rather than pace - is a bit predicated on him not being mowed down. Think he'll struggle more than Ekitike who people assumed would do poorly but feels a much more natural match to PL football.
