Gerard Pique urged Barcelona to continue fighting in LaLiga despite trailing leaders and rivals Real Madrid.

Having won back-to-back league titles, Barca are four points adrift of Madrid after a 4-1 thrashing of Villarreal on Sunday.

Pique called for his side to keep pushing ahead of hosting Espanyol in a derby clash on Wednesday.

"We don't like to be behind in the standings, but we will fight to turn the situation around, knowing how complicated it is," the Barca defender told Movistar.

"We will fight to the end."

After a Pau Torres own goal and Luis Suarez strike, Antoine Griezmann scored his first goal since February, and Ansu Fati sealed Barca's win late on.

Pique hopes Griezmann, who has netted 15 times this season, gains confidence from his goal.

"Playing in this way makes the three of them [Lionel Messi, Suarez and Griezmann] closer to the goal," he said.

"We feel more protected. In addition, Antoine's goal is very important so that he is confident."
