Djibril Cisse believes Queens Park Rangers' battling performace in a 2-1 defeat by Bolton Wanderers is a sign they will beat the drop from the Premier League.
The French striker returned from a three-match ban on Saturday to score his second goal in three games since his January move from Lazio.
But it was not enough to prevent a narrow loss at Bolton that sucked Rangers into the drop zone.
Cisse told the club's official website: "With this kind of performance, there's no doubt that we are going to stay up.
"We have to produce this every game and we have to score goals. We have to fight until the end and that's what we are going to do.
"I love challenges and I love the club already. I will do my best to help the club stay up because we belong in the Premier League now."
Cisse, however, admitted QPR shot themselves in the foot defensively for Bolton's winner.
The 30-year-old, who had earlier equalised, said: "I am happy to help the team, but when you don't bring the points home, it's a bit useless.
"With five minutes to go, you cannot really concede a goal like that. It's not only the defenders who defend, it starts with the attack. The whole team should have done better."
QPR sit third-bottom on 22 points, one behind Bolton, who occupy the first spot above the drop zone.
