Arteta is being linked with tomorrow's opponents Arsenal.
Gabriel, who has five goals in three games for Pep Guardiola's side, already believes Arteta has the quality to step out of his boss' shadow.
"He's helped a lot of players. When I want to do finishing after training, I tell him and he comes and helps me," the Brazilian said.
"So he is really fantastic for us. All the players know that — everyone knows that in the club. He is a fantastic guy and fantastic manager.
"I don't honestly know what he thinks about his career, that is for him. I hope he can find his way and I hope he can be happy."
