Barca and the Reds will face-off in the Champions League semifinals.
Valverde stated: "Liverpool is a very powerful rival with a nice attack.
"They reached the final last year, are in the semifinals this year and are fighting for the Premier League crown. It may be a very attractive match for them, for us, and for the general public.
"That said, there is still a lot of things to do before Liverpool in ten days, and we have some very important league games to come.
