Maybe Real don't have super star in the team any more but I feel they have better team than Barcelona.
I think they have some players that can be categorized as superstars. Ramos, Marcelo, Modric, Kross, Hazard, and Bale are top players in the world. Especially Modric, he ever won Ballon d'Or in 2018. It is undoubted to call him a superstar.
Their defense is much better than in previous years.
The defenders may be better than previous but it is not enough to win a match if they have no shining attackers. Moreover, to win La Liga trophy, Real Madrid must have good players in all positions, defenders-midfielders-attackers.
Barcelona have a lot internal conflicts now and depends to much on Messi.
Even if they have internal conflicts but if they can win all remaining matches, they still can win the trophy. I don't think the internal conflicts of Barcelona really bring negative impacts on their match. While the problem of Real Madrid attackers can give big impacts.
Well, in my opinion we have today many stars but only 2 superstars, Messi and Ronaldo.
We can see what happened with Real when they lost Ronaldo.
Their defense is still very good but they don't have good attackers any more, someone who can replace Ronaldo.
I still think that Real have more chances to become champion because they are team while Barcelona is often "one man" show 😀
Any way, we will soon find out 😁
