The youngster admits things are difficult for the Catalans away from home, but warns Barca will not give up on reclaiming the La Liga title despite Real Madrid's lead
The Catalans have been struggling to find their best form away from Camp Nou in 2011-12, but Cuenca has stressed that they should not look for excuses.
"Osasuna's pitch is small but we knew that coming in. We shouldn’t look for excuses," Cuenca was quoted as saying on the club's official website.
"It’s normal that it’s more difficult for us away from home. The Camp Nou is bigger and the ball rolls on the pitch better.
"I wasn’t able to see if it [Alexis Sanchez's goal] was offside or not, it was a really fast play. We know what kind of team we are and we must keep on fighting until the end."
The youngster then looked ahead to Tuesday's Champions League round of 16 match against Bayer Leverkusen.
"We’re going to Leverkusen with a lot of enthusiasm to try and win."
