A stalemate does not mean the game is boring. It seems you guys only considers lots of goal as an exciting match. If you look at the stats, it's quite balanced, but ATM xG is higher. I kinda get the same feeling like the City vs Liverpool match where both of the team are aware of each other strengths and try not to give any chance to create a score.
La Liga table is getting interesting, the top eight has one point between each of them. Need to beat each other to move up in the table. Nice.
Big matches like these get quite cagey at times as both teams don't want to lose at any cost. Given both teams lost their champions league matches to big opposition makes them more cautious in their approach. Real madrid are not performing even with additions like Hazard. So i understand why they dont go all out to win a big match.
I totally agree with you as lot of time i have seen this type of hype matches mostly go without goal as both team dont want to lose the match and play defense game. That is why always going under goal in this type of game gives good profit
