Although they grabbed a surprising 2-0 win over Manchester United on the last day of their 2018/19 Premier League campaign, Neil Warnock's side endured a dismal season in the top-flight and are now preparing for life in the Championship - yet again.
Here's a look back at the season as a whole and an overall grade for the report card.
Cardiff's fate in the league was sealed after they suffered a 3-2 defeat to Crystal Palace in early May; their 11th home league defeat of the season.
Spending only £29m in the summer of 2018, the Welsh side struggled to offer much quality in attack throughout the campaign; scoring a measly 34 goals all season.
