The Reds only managed a 1-1 draw with Manchester City at Anfield on Sunday and are seven points adrift of leaders Manchester United.
“When you are playing catch up, you have to win so we are disappointed, obviously,” Benitez told Sky Sports.
“You never know. Each game you have chances. Chelsea are speaking that they still have a chance, so we also have a chance.
“We have lost two points, but we can win our games and we still have to play at Old Trafford so we will see.”
