I can see Sociedad was slightly dominate the match but seems Real Madrid is playing more affective than Sociedad and finally Ancelotti was playing Arda Güler since the beginning of match and Arda Güler didn't missed that opportunity and performing well even he was scored the only goal in this match and bringing Real Madrid to collect 3 points from this match and indeed after this winning Real Madrid can wided their gap points with Barcelona became an 14 points and if i am not mistaken mathematically Real Madrid only required 2 wins again to lock their current position and being an the champion of this season
Basically we are talking about a situation where this dude has taken advantage of every single game that he played. If he is still not getting any chance at the league (I can understand not playing at UCL) when they already guaranteed the league title, then they are making a mistake. I personally believe that he should definitely go to a team that will play him all season for every game on loan, then come back to Real Madrid as someone who played 40-50 games in a season, if he doesn't get injured then he would be a lot better.
