It is very difficult to ensure that this match will be easy for Real Madrid, because Villareal is clearly also in promising form. In fact Villareal will make it more difficult for Madrid to get 3 points. The last time they met, both had a goal party of 4-4, this draw is of course still quite ideal as a reference considering the unstable condition of Madrid front line in creating its best game. The defeat in the Champions League is an important note for Carlo Ancelotti because until now with the best striker composition, he has not been able to provide satisfactory results.
Villareal are at a third position in La Liga table and they have only one point less than Real Madrid. Their ranks and very small point difference make their direct match more interesting. I disagree with you and think that Real Madrid will win this match.
I look at two things, total goals are the same for two clubs with 17 goals, but in conceded goals Real Madrid got 6 and Villareal got 15. This shows Real Madrid have good defense but Villareal have very weak defense. This will be their dead weakness in a match with Real Madrid that have very strong attacking power. Villareal not only have risk to lose this match but also have risk to get a big defeat.
