Yes, I believe so too. Based on H2H so far between Osasuna vs Real Madrid, RMA dominates the victory. Even in the last 6 matches, RMA won 5x and drew only 1x. While now, Real Madrid's position is quite on fire, and they are required to win in order to maintain their 1st place in La Liga. So, Ancelotti must be serious in this match.

The quotas are also totally in favor of the team coached by Ancelotti, Real Madrid.
There is a huge difference between the two teams, it was obvious that it ended in this way, unfortunately.
In fact, i am considering making a multiple bet in the La Liga, it takes me a lot this week.
