Summer signing Dejagah knows the Cottagers will need to show a grittier side at the Britannia Stadium if they are to get a positive result.
"The players tell me that Stoke are very direct and it's not easy to play at their ground," the winger told the club’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."
