Barcelona will be hoping to carry their superb start in the Primera Division into their defence of the Copa Del Rey on Tuesday night.
Manager Tito Vilanova has seamlessly taken the Catalan giants forward following Pep Guardiola's resignation at the end of last season.
They equalled their best ever start to a league campaign by thrashing Rayo Vallecano 5-0 on Saturday evening but they will now shift their attentions to the domestic cup competition when they visit Alaves in the first leg on Tuesday.
But despite facing third-tier opposition, David Villa, who scored Barca's opener against Vallecano, is refusing to underestimate Jose Carlos Granero's men.
"We proved that we don't tire easily. The daily work is vital and we have the same attitude that we've always had," the striker told his club's official website.
"I'm very pleased with how everything is going, I was able to help the team and I'm getting more minutes each time we play.
"Victories don't come easy. In the Copa, against Alaves, we need a good result because it's a difficult stadium and they'll be very focused."
Alaves' fellow minnows Llagostera welcome Valencia on Tuesdy and boss Oriol Alsina is relishing the clash.
"Now I think we can all party on Tuesday in this tournament to come," he said on Llagostera's website.
Valencia have struggled for consistency in the league this season, losing three of their last five games and Los Che sporting director Braulio Vazquez has urged his side not to take Llagostera's challenge lightly.
"We have to go out there to compete with respect, even if we think we are favourites," he said.
Alcoyano president Juan Serrano is confident his side can produce a stunning upset when they host Real Madrid on Wednesday evening.
The Segunda Division B side have been in decent form of late and Serrano believes his side should not be underestimated.
"If we can survive the game at El Callao, we will prepare for Madrid," he told AS.
"I believe that 80 per cent of the tie will be decided at El Callao. If (Madrid boss) Jose Mourinho is smart, which I do not doubt, they will come here with all their artillery and not reserve anything for the return at the Bernabeu."
Primera Division joint leaders Atletico Madrid travel to Jaen, third-placed Malaga visit Cecereno and Almeria welcome Celta Vigo.
The only all La Liga clash sees Real Zaragoza host Granada in the first leg while Osasuna will make the trip to Sporting Gijon on Thursday.
