The Hoops are coming off the back of a 6-1 defeat at Chelsea, in which Cisse scored the only goal but the striker says the team must move on quickly and focus on their next game.
The 30-year-old insists the squad will stick together to boost their survival hopes.
“The plan now is to lift one another this week,” he told the club’s official website.
“We will all try to help each other to be ready for Sunday because it is a big, big game.
“We have all week to prepare ourselves and what is encouraging is that our home form is really good. That is what we need to concentrate on and work on.”
|9/1||QPR are 9/1 to beat Stoke City 2-0 this weekend with sportingbet|
QPR have won their last four games at Loftus Road, including victories over Arsenal, Liverpool and Tottenham.
Their last game of the season is away at Manchester City, which puts a lot of emphasis on the Stoke game, but Cisse welcomes the added pressure.
He continued: “I like it when there is pressure.
“The manager will have to make his choices about who plays but whether you are on the pitch or on the bench you must be ready.
“Everybody in our dressing room must show what we are made of. We have a lot of characters and we must all do our bit.
“We must win this game, there is no other choice.”
