The streak started a year ago this weekend, when Luis Enrique was still in charge, after Barca were beaten by Malaga at La Rosaleda.
After the interval, Barcelona's measured close to the first half seemed to carry over into the second, with Valverde's men offering little urgency in possession and remaining content to maintain a controlled tempo.
Barcelona have already beaten them in La Liga and the Copa del Rey this season, and one more will see the club make history.
"They are important records and we can achieve something with a win or draw tomorrow".
Ernesto Valverde says Lionel Messi is the best, and is not likely to bench him despite injury problems. "It's been hard, very difficult".
"It's a record that's been there a long time so it's hard to match it, obviously, but we have a chance of doing it".
Barca are now 12 points clear of nearest challengers Atletico Madrid at the top of the table ahead of Diego Simeone's side facing city rivals Real Madrid in Sunday's derby, as title glory moves closer for the Catalans with only seven games to go. "We haven't won anything yet". If we win, then we will only need 12 points.
Messi's treble took his tally of league goals for the season to 29, while he's now scored from outside the penalty area in each of his last six league outings.

Denise Bode, a tax and trade expert at a Washington law firm, said a full-blown trade war is possible but it is more likely Mr. Investors were aggressively selling stocks such as airplane maker Boeing and heavy-equipment maker Caterpillar.
"We think he's fine and scoring goals always helps everything", Valverde said of Messi's health after the game at Camp Nou.
"Neymar is really more of a Messi-style, one who constructs the play, but scores the goal also".
"Now we have the best, the most handsome, but also the most hard games ahead".
Nabil El Zhar got a goal back for Leganes after the break as Barca's performance dropped off significantly, but the hosts made sure of victory when the magnificent Messi grabbed his third three minutes from time.
"No, we're not thinking about that", the coach said.
"It happened against Athletic [Bilbao] and Roma, too".
"We know he has the talent, but he has to work at the other things". "After a great first half, we're left with the sensation that we put ourselves in danger slightly". We have to maintain our rhythm better than that.
