The West London club, who defeated leaders Wolverhampton Wanderers on Saturday, extended their unbeaten run to 12 matches with an eighth successive home win.
Mitrovic added that "nobody" likes the way that his side play after scoring his first goal for Slavisa Jokanovic's men at the weekend.
"I think everybody since last season is scared of Fulham," the Serbian told FulhamFCTV. "The way we play I can say nobody likes it, because we play with a lot of possession and we create a lot of chances every game, so I think any team in the Championship doesn't like to play against Fulham.
"Twelve games unbeaten is an important thing as for the confidence and mentality of this team as we look forward and try to win every game. They know my qualities, they know where I'm strong so they try to use me. My first goal at the Cottage was a nice feeling and I hope I can continue with this.
"There's a lot of games to play until the end of the season and we'll fight for second place. Against [Aston] Villa [it] was unbelievable, today was unbelievable and I hope the [fans] will stay behind us for the rest of the season because we need them."
