Real Madrid will have no difficulty facing Osasuna moreover they will start the match at the Bernabeu. Real Madrid will win the match easily because the quality of the players Real Madrid has is better than Osasuna. The international break will not make Real Madrid's quality decrease even though some Real Madrid players have just exhausted their energy to defend their country. I think Real Madrid will party in this match, my prediction is Real Madrid will win 3-1.
Their differences are still too far apart even though at the beginning of this season Osasuna actually appear still in quite good quality but indeed their opponents Madrid are on a different level.
This is difficult because in any case they will not be free especially when looking at Madrid's midfield at the moment.
There is no worry for Madrid now, especially since Benzema might be able to play again.
