Benjani Mwaruwari is backing Portsmouth teammate David Nugent to soon prove the doubters wrong.
Zimbabwe star Benjani said: "He will definitely score goals soon. He has the ability and all he needs to do is keep working hard. I know, course, how difficult it is when you come into a new team and are unfamiliar with the players alongside you."
He also insists Portsmouth do not view their trip to Stamford Bridge as a lost cause.
"This is the second of four big games for us and we did well to take a point against Manchester United," he said.
