The Dutchman said that, while there was euphoria in the dressing room, the Anfield club must now fully concentrate on Manchester United.
Kenny Dalglish’s side knocked Manchester City out to progress to the Carling Cup final on Wednesday, but face another Anfield showdown with United in the FA Cup fourth round.
“We can be happy about what we have achieved in reaching Wembley,” Kuyt told the official Liverpool website.
“But we have to put that aside because there's another massive game coming up on Saturday against Manchester United and it would be great to knock them out as well.”
The clash with United will be a high-profile affair following the investigation and subsequent ban for Luis Suarez, after he was found guilty of racially abusing United’s Patrice Evra.
Both clubs have released statements asking fans to concentrate on supporting their respective teams and to refrain from abusing players.
The Old Trafford side may have an advantage through not having to play in midweek, whereas this will be Liverpool’s second high pressure game in a week.
Kuyt does not believe this will be a factor and cites the club’s long experience of Champions League and Europa League football as to why they can cope.
“I think we are used to playing every three days from when we were playing in Europe in the Champions League,” added the Holland international.
“We were playing big games every two days and that's what Liverpool Football Club should be about.
“It's great to have two great games in a week and, like I said, we are all focusing already on the next game and we're desperate to win it.”
