La Liga is getting a bit boring to be honest. Seville is far behind Real Madrid and the rest are nowhere to be seen. Perhaps is becoming more fun to watch the games of the teams in the middle table rather than watching Madrid grinding everything on its path. I would have never thought at the beginning of La Liga that it would play out this way: Barca was very well caught off-balance and everyone knew so, but the dominance of Madrid in my view was not something that could be expected since they were also impacted by the loss of Ronaldo and nobody could predict how the rest of team just step up easily and do great.
As a Real Madrid fan, I'm happy to see Real Madrid leading the way but it's true like you said, when there is no strong enough competitor to fight for the title, then the competition will be boring. La Liga still has a long way to go, I hope big teams like Barcelona and Atletico Madrid can recover from their slump so that the title race becomes even more excited.
Even I who don't have a favorite team but still feel happy to see Madrid so far, because in the beginning Madrid didn't go well for this season but who knows. Madrid can show positive results with their new coach this season, so with this achievement I think it's still quite interesting. Also, although Atletico and Barcelona may recover in the near future, they basically won't be contenders for the title race this season, but since you said La Liga is boring because Madrid already have the top spot. At least we can still see competition for the top four spots at least for the 3rd and 4th positions, because with Atletico and Barcelona still out of the top four. So of course, La Liga will still be interesting until the end of the season considering the hunt for a top four position which will be a competition with the rise of Atletico and Barcelona.
