The Blues, who have endured an up and down season so far, have turned things around under caretaker boss Roberto Di Matteo and Ramires insists that the final couldn't come at a better time.
"We have now entered the decisive phase of the season," he told Goal.com. "We are achieving a lot more than people believed.
"In terms of morale we have grown over the last few weeks and the final comes at perhaps the best possible moment, although we won't be complacent.
"Liverpool are a difficult rival, one of the hardest teams we could have got, which would make winning the FA Cup even more impressive."
Chelsea have lost both meetings with Liverpool so far this season.
