Real Betis this season has only been quite good in their defense. But in building attacks I think Real Betis will not be too dangerous for Real Madrid's defense. Because I see their squad is not very good at building attacks. Indeed, Real Betis has had more draws this season, with 15 matches we can see that Real Betis has achieved 7 draws. Which means almost half of all matches are draws for Real Betis. Honestly, I don't know whether this is a good thing or not. But yeah, Real Madrid can't be careless in this match. Because Real Betis, which has a fairly strong defense, and could build a quick counterattack and overwhelm Real Madrid.
But I'll probably still bet on Real Madrid. Because I see that Real Madrid has many advantages over Real Betis this season. So I think Real Madrid will win even if only by 1 or 2 goals.
Real Betis dominance with defensive and not offensive regarding with their goals winning ratio from 15 matches in La Liga, Real Betis goals scored productivities dropped drastically than other La Liga teams on the top six standings position. Scored 18 goals of 15 matches is not good achievement for Real Betis with wining ratio every match 1 or 2 goals and have one winning match above 3 goals against Valencia. I think difficult capital for Real Betis upcoming match against Real Madrid have more aggressive when attacking counter.
Real Madrid have more solid with defensive by conceded 9 goals and success scored 33 goals of 15 matches, with home match seems Real Madrid more favorable team than Real Betis on matchday 16.
