Real Madrid are within touching distance of table-topping Barcelona but veteran goalkeeper Iker Casillas said he would take the UEFA Champions League title over La Liga.
Only two points separate Real and Barca with four matches remaining in La Liga, after both teams claimed respective wins during the week.
Carlo Ancelotti's Real are back in action on Saturday as they prepare to visit fifth-placed Sevilla, who are still in the hunt for Champions League qualification.
"The coach already pointed out that the Champions League is easier to win," Casillas said on Thursday.
"The Champions League is still in our hands whilst the league title is currently in Barca's hands. The last four teams remaining in the Champions League all have a 25 per cent chance of winning.
"Traditionally Madrid fans prefer European competition and winning the highest honour in Europe for the second year running would be special as it's never been done before."
Lionel Messi and Luis Suarez both scored twice during the week as Barca's unbeaten streak in all competitions extended to 15 games.
"The season so far is excellent. Based on the results, we're back on the path to excellence," Barca president Josep Maria was quoted as saying by Marca.
"The team is highly motivated; we've managed to put together the best front line in the world, and all under a new coach."
