9 games remain. Thankfully Madrid were awful in this last couple months so we still have a very comfortable cushion of 11 points. Good we won the Clasico as it could have been a lot more dicey.
To lose the title we would have to lose 4 out of the next 9 games or some similar loss of points whilst Madrid would need to win every one of their 9 games remaining, which neither situation seems that realistic to me.
For our attacking woes we do have a very good LaLiga defense scheme, keeping like 20 clean sheets in 29 games, and we have only lost 2 LaLiga games all season, so we would have to make a monumental collapse to choke this lead.
Madrid on the other hand are balancing a CL campaign with their league games and never been consistent enough to win 9 on the trot (in fact, Atletico are close to overtaking them and might even end up 2nd themselves).
So LaLiga is basically still in the bag as we would have to go on an abysmal run of form to choke it.
Only realistic scenario where we somehow do that badly is none of the currently injured players return in good time and we have more injuries to key players (Araujo/MATS being most important at the moment).
