Mo Diame says he happy to remain patient as he waits for a chance to impress Newcastle boss Rafa Benitez.
The 30-year-old is yet to make a start this season, but he has made five appearances as a substitute.
"I just have to be patient and keep working and show at every single training session to show that I want to play," the Senegalese international said.
"When I come on, I need to show that I'm ready and I want to play like everyone.
"To be honest, he's [Perez is] playing very well. To be honest, all the team is doing a great effort.
"We've started most of the games with the same XI, because they have been doing brilliantly. If they are doing brilliantly, it's good for everyone, because I need to work harder for the team."
