The Blaugrana midfielder has discussed how fighting on numerous fronts is not an easy task, while also commenting on how the current set of players will miss Pep Guardiola.
Although the Blaugrana missed out on the UEFA Champions League and La Liga titles last season, the Spain international enjoyed personal success, recently winning UEFA's Best Player in Europe award over the likes of Lionel Messi and Cristiano Ronaldo after helping Spain win Euro 2012 on the heels of another strong season with Barcelona.
"It appears that when you win everything, it seems normal and easy, but it is very difficult," Iniesta told GolTV. "The challenge is wanting to improve, wanting to keep winning championships."
While Barcelona has enjoyed a solid start under Tito Vilanova, Iniesta acknowledged that the squad does miss former coach Pep Guardiola.
"With him we reached the top and also we enjoyed ourselves a lot," Iniesta said. "I think that's paramount. We enjoyed everything, every workout, every game, and we learned a lot and will miss him in that sense."
