The Cottagers have been one of the more entertaining teams in the Premier League this season with 25 goals in 12 matches.
However, summer signing Dejagah says that they will struggle to play their usual game against their "very direct" hosts at the Britannia Stadium on Saturday.
"The players tell me that Stoke are very direct and it's not easy to play at their ground," the 26-year-old told Fulham's official website.
"They have some big players and they like to play long balls.
"We must fight in this game - it's not a match to play football. If we fight for each other we can win this game."
"The right is my favourite but I've played on the left before for Wolfsburg. The manager is the boss and he will decide who will play there on Saturday."
