changed their manager three times before Nedo Sonetti, appointed in November, was able to save the team from relegation, especially thanks to the excellent goal contribution from Honduran striker David Suazo. Apart from finishing 9th in 2008–09 season, Cagliari regularly finished in the bottom half of Serie A under a sequence of managers, before being relegated in 2014–15. They gained promotion back the following season as champions of Serie B.

The blue part of the stemma features the sky and the sea, also a castle; this is because the old historic centre of Cagliari is walled and called the Castello. Due to the use of these colours on their shirt in halves, the club is commonly nicknamed rossoblu. Cagliari have had several different logo designs during their history, all of which feature the
