The 2011–12 Spanish football season was the first for CE Sabadell in the second level since 1993, when the team was relegated for not paying its players. After a stunning season in Segunda División B, the team promoted via play-off and was runner-up in the overall season, being surpassed only by Real Murcia (also promoted), who won on penalties in the play-off final matches (agg. 1–1 a.e.t, 8–9 p.s.o). During early June, Joan Soteras confirmed that the team manager, Lluís Carreras renewed for this season after the rumors emerged in April that linked him with FC Barcelona B.
Sabadell finished the season in 19th place, which would normally have resulted in an immediate return to Segunda B. However, they were reprieved from relegation when Villarreal were relegated from La Liga at the end of the season. Villarreal's relegation from La Liga meant that their reserve side, Villarreal B, would automatically drop to Segunda B.
^ abcBecause of the tight schedule, and given that any Liga Adelante team would compete to win the Copa del Rey trophy due to its early defeat, LFP approved on 18 January the television operators request to postpone the Matchday 30 to 23 May, between the Matchdays 40 and 41.
^The team that wins this variable will be qualified ahead of another with the same points but lost on goal average. If the goal average is drawn between two or more teams and, at the end of the season these teams have the same points, the overall Liga Adelante's goal average prevails over this goal average.
