"It is great news for the club to be able to continue to improve, independent of whether we win trophies or not. Barcelona always has to improve," he continued.
Having already been eliminated from the Champions League and defeated in the Copa del Rey final, Barca now have only the league title to play for but lie four points behind Atletico Madrid in second place.
Despite the pessimism among the club’s fans, Iniesta insists that Barca will keep battling to win the championship in their remaining games.
"For me failure is when you try to do things and they do not come off, but we are still trying and we will keep going until the end," added Iniesta
"There is still some possibility if we win all four matches, but the worst thing in football is not to have to be able to depend on yourselves."
