Fulham manager Martin Jol has admitted that he has yet to decide on a regular strike partnership.
The former Tottenham Hotspur boss has switched his forward players Dimitar Berbatov, Bryan Ruiz and Mladen Petric on occasion this season in an attempt to find a settled starting XI.
"What I felt [against] Everton is that Bryan Ruiz and Berbatov would be the best combination, but I know for a fact that Petric is one of our most gifted players, so it's not easy," London24 quotes Jol as saying. "We have to change the system to play them all."
The Cottagers travel to the Emirates to play Arsenal in the Premier League this weekend.
