Petric, who scored twice in that encounter on his debut, has recognised the need for Fulham to continue to pick up points after the win over West Ham United.
"We will see what sort of game it is," he told the club's official website. "It's always different with home games and away games. Of course, I hope we can play like we did in the first game against them.
"We still need some points. The game against West Ham United was very important for us."
Fulham are currently 13th in the Premier League.
