Barcelona sit top of La Liga, 10 points ahead of Atletico Madrid and 14 clear of Real Madrid, and Valverde wants to maintain as big a cushion as possible with 13 games left to play.
"When you win in this fashion, it seems that everything is a bit more relaxed but I think in that sense it's good for us from the point of view that we have been able to rest a few players," Valverde told the official Barca site.
"We have been able to make a few changes during the game because we have got an important week coming up. We enter into the decisive phase of the championship where the points count for a lot, and we want to keep our rivals at a distance."
Barcelona travel to Las Palmas on Thursday before facing second-placed Atletico at Camp Nou three days later.
