Not a problem @Steph89_Travel
I haven't been to the football club (not my thing really) but the other sights I did enjoy a lot.
More info on the Magic Fountain can be found here. It is a night-time show with a bit of music if you and your partner wish to dance a bit as well.
I forgot to mention that while walking around Barcelona, you may want to design a route that brings you to these buildings.
Hope that helps.
