Both Aubameyang and Sterling has been criticised for their performance against Manchester United.
The Blues had a hard time in passing the ball to their forwards but even opportunities came the duo failed to take any meaningful chances.
ESPN pundit Stewart Robson believes their underwhelming performance has put more pressure on the manager to take risks in midfield.
“It’s a problem,” the former Arsenal midfield told ESPN FC.
“When you see Sterling played for Chelsea [on Saturday], I thought he was really poor.
“He got himself in some good positions, but his final decisions and actual control weren’t particularly good. He wasn’t making the right runs.
“Aubameyang, he’s the player I saw at Arsenal in the last couple of years where he’s not that really effective.
“Potter is a good coach. I think he knows how he wants his side to play.
“But unless he can get somebody to play in that centre-forward position, he’s got to do a lot of tinkering in midfield to create more chances, so at some point, they will score a goal.”
