Bent said that the Londoners have shown "glimpses" of what they can do this season but that they must perform to a higher standard on a more consistent basis.
"The defeat against Cardiff was, as you'd expect, very difficult to take," Bent told the club's official website. "When you lose a game so late in the day, it's always tough. It wasn't our best performance, but I thought a draw was probably the fair result.
"Obviously you have to do your best to move on, and that's been the focus this week – we want to put things right against Stoke this weekend. We know that we have more to give, and I think we've seen glimpses of that so far. It's just a case of it coming together for us.
"If we can string a couple of victories together, then we'll soon be pushing ourselves up the table. We all share that belief; it's a good group here at Fulham and we're in it together. That's really important."
Fulham are currently in the bottom three of the Premier League.
