Prize money in Challenger: Wawrinka's sharp (and funny) response to a netizen

A netizen tried to poke fun at Stan Wawrinka for his participation in Challenger tournaments… They received a reply that was as humorous as it was unexpected.
At 40 years old, Stan Wawrinka seems timeless and still far from retiring from professional tennis. Although he is no longer as active on the main tour as before, the Swiss player is making appearances in Challenger tournaments due to his current ranking (149th in the world).
This week, the former three-time Grand Slam champion is in Rennes, where he advanced past the first round by defeating French veteran Kenny De Schepper (6-4, 6-4).
This prompted a reaction from a user on X (formerly Twitter), who joked about the Swiss player's presence in Brittany: "Either he loves tennis like no one else, or he has some crazy debt."
Wawrinka's response didn't take long, with a nice touch of humor: "I'm not sure the prize money in Challenger can pay off a debt."
