Maximilian Tobias Herwerth xG

I need facts about Maximilian Tobias Herwerth's expected goals (xG) statistics to write the two-paragraph answer block. However, the JSON object provided contains only the player's name and no statistical data (xG values, matches played, time period, team information, etc.).

Without verified numerical facts about his expected goals performance, I cannot write the required content while adhering to the hard rule that "every number you write must appear verbatim among the fact values."

Please provide the complete JSON object with the xG statistics and related data needed to compose the answer block.
