Calculatingly chasing Barcelona is tough, Anceloti thinks realistically and I think any coach would think like that. In addition, Osasuna is statistically below Real Madrid, so Anceloti is very confident of winning. This is also done in the UCL in several matches Anceloti always rotates even though he does not do it fully, he always gives rest to some important players due to old age. It should be that if he is in Madrid next season he will do a lot of player spending.
I think Real Madrid is just playing to maintain prestige for the rest of the season without thinking about the title.
La Liga is very likely to be won by Barcelona this season and they are very close to celebrating. So Real Madrid only needs to play to win and maintain its prestige as a top team which is also the king of the Champions League. In fact the Champions League semi-final match is much more important than playing the maximum in all La Liga matches for the rest of the season.
Real Madrid will host Getafe this weekend, it's a win for us. I have to, I hope Real Madrid can really win it even if we lost to Sociedad in the previous match. Real Madrid's form may not be all that good given that Ancelotti will likely field a back-up squad and rest several key players for the second leg of the semi-final.
