How does the football club wash clothes?

Professional teams, especially big clubs, have special laundry staff; Responsible for cleaning the players' clothes; Players' clothes are not changed every game, and sometimes they need to be cleaned by a laundryman when they are dirty;

Manchester United fans have a joke to laugh at Berbatov:

"Manchester United's laundry staff like Berbatov best, and his jersey is cleaner than Van der Sar's"

This joke is used to laugh at Berbatov's laziness on the court, which also proves that even a giant like Manchester United needs laundry staff to clean clothes instead of changing clothes on the court.
