Chelsea host Manchester United tonight sitting in sixth place on the Premier League table, seven points outside the top four.
"That's the great thing about the quality we have in this team," he said.
"We're capable of a run, but capability is one thing and producing it is another. Time is running out, so we need to be as close to perfect as possible in every aspect of the game.
"If we do that, we have the potential to win every game for the rest of the season."
Rosenior also insists he can see a character in his team which can match the greats of the past.
He added: "When the team was its best with players like John (Terry), Frank (Lampard), Didier (Drogba), it was a team of big personalities fighting for the shirt, not a team of egos.
"I feel we have those kinds of characters in our squad, and that’s what we need to show in this moment."
