Rafael Nadal criticized fans for showing a lack of respect at the ATP Cup.
Nadal lost 6-2 7-6 to Novak Djokovic.
"Honestly the crowd was fantastic every single day but sometimes people from some countries, they probably don't understand how tennis goes," Nadal told reporters after the loss.
"They think it's (like) football and stuff and the atmosphere in tennis is different. The respect for the players should be there and at some points I think the respect from a small part of the crowd (wasn't) there."
