The Dutchman feels the Blues are growing in spirit, as they aim to go for the domestic and European treble.
The Blues have a 3-1 advantage going into the crunch match on Tuesday at Stamford Bridge, meaning Liverpool have to score three goals without reply.
Hiddink, who is only in charge at Chelsea until the end of the season, believes that his side are in the right frame of mind at the business end of the season.
Speaking to Sky Sports, Hiddink said, "There is a fantastic spirit around this club at the moment - everyone believes in what we can achieve this season and it is exciting to be a part of that.
"But we must not lose our focus for one game or one minute, and that means each game is as important as the next one. We have the same aim, which is to try and win all of them.
"It is important that we take the momentum gained from winning at Anfield into this game and keep our level of performance up."
The former PSV Eindhoven manager has stated that even if the Blues win the Champions League, it would not be enough to persuade him to stay on into next season, as he wishses to concentrate on getting Russia to the 2010 World Cup in South Africa before retiring after the tournament.
