Paulinho, who arrived from Corinthians earlier this summer, admits that he is uncertain as to whether Bale will still be a part of Andre Villas Boas' squad this season.
"I sincerely don't know, but I think this is something more private for Bale, he doesn't tell me anything," he told Fox Sports Brazil.
"But I hope he continues with us, so that he can help us. He is a great player and achieved great stats last season, so I hope he stays with us."
