Mathijs Tielemans xG

I need facts about Mathijs Tielemans' expected goals (xG) statistics to write the answer block. However, the JSON object provided contains only the player's name and no actual statistics data (no xG values, matches played, time periods, or other numerical facts).

Without verified facts containing specific numbers, dates, or performance metrics, I cannot write the required two-paragraph answer block 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 for Mathijs Tielemans.
