The LaLiga champions will meet Jurgen Klopp's men in the Champions League semi-final first leg to be played at the Camp Nou on May 1.
Ernesto Valverde is cautious of the possible problems Liverpool could cause Barcelona in the Champions League semi-final.
The Barca boss recognises Jurgen Klopp’s Reds, who were runners-up in Europe's top club competition last season, are a "very powerful" side, and expects major tests from the front three of Mohamed Salah, Sadio Mane and Roberto Firmino.
"Liverpool are a very powerful opponent. Offensive players have been showing their potential in the last two years," Valverde told a news conference on Friday.
"Last year they reached the final. This time they're having a great tournament. They are also fighting in the Premier League.
"It's a very attractive game for them, for us and for the public. It will be very hard, for them and for us.
"The final is just there and we'll give our best to reach it."
