Barca won all six trophies that they competed for this year.
And Ibra says: "Before this season, nobody said that a team could be capable of winning it all. It's incredible and it is difficult to believe it could happen, but I think we can repeat it.
"I've been lucky to be here only half of the year and in that time, to win three trophies. Within a few months I think it's possible I'll be able to do even better."
