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.
I totally agree with you because Real Madrid has been on there good performance since the beginning of this season, however I no that there previous meeting with Real Betis was not that impressive and encouraging because they ended up playing draw but that was when Real Madrid was still finding it difficult to perform this season, but since they have fully come back to there impressive form I'm very certain that they would win real Betis with many goals different. Because for Real Madrid to have entered the first position on the league I'm very sure that they can not afford to lose any match.
It's normal for a club to have a bad situation in one match, we can't demand that they can still win all matches because many factors will affect that, one of which is luck. Real Betis is a difficult opponent for Real Madrid, especially this is a home match for Real Betis, of course it wil make them even more excited to be able to win the match against a strong club like Real Madrid. But with Real Madrid's current situation, I'm pretty sure they will be able to bring home full points from Real Betis headquarters.
