I think Real Madrid is stronger than Barcelona right now. Real Madrid has great team with many stars while Barcelona is building new team with young players. It is good that Barcelona is thinking about future but it is hard to see them beating Real Madrid experienced team soon. I think Barcelona needs time to develop their young players and maybe in one season or two they can catch up with Real Madrid. But football is unpredictable and Barcelona new team might surprise us with some great games.
It cannot be denied, with all the problems that the Barcelona team is currently facing, it is making it difficult for them to get up and keep up with Real Madrid.
The financial problems experienced by Barcelona mean that they cannot bring in quality players to match Real Madrid and Barcelona management has said that they will build a team with young players, it will take several seasons to get their best performance, so of course the two giant teams La Liga is now beyond comparison.
