The loss to Arsenal was Madrid's 12th defeat in all competitions this season, 10 more than in the entirety of last season. It has been a miserable campaign for Los Blancos, having lost to Barcelona (twice), Liverpool, Arsenal (twice) and AC Milan, as well as others domestically.
There is every chance Real Madrid end this season without winning a major trophy; they have already been ousted from the Champions League, trail Barca by four points in La Liga and face them in the Copa del Rey final next weekend, where the Catalans are favourites to lift the trophy. It's not just the number of defeats, but also their nature which has left Madrid fans in despair and Ancelotti's job in real jeopardy, even though he has a contract until 2026.
