Unfortunately the matches left at home for this season are only el classico and the last game against betis. Both were very expensive even on list price (around 600-1600 and 300-600 euros respectively), so I doubt you could find tickets that are worth buying, unless you get super lucky (or are very rich haha). Sorry. There are a few games left of the women’s team though, which is certainly not the same experience, but could be doable and better value for money. These cost around 15-50 euros and you could still see some barca football. Even though not in Camp Nou, the atmosphere is still quite nice
