Atletico Madrid missed out on securing a place in the Champions League after beating Atletico Bieber 2-0 on Saturday.
Atletico Madrid see La Liga title taken by bitter rivals Real Madrid Diego Simeone's men started slowly and Mario Hermoso was sentenced within 10 minutes for injecting Inaki Williams's cross into his own net.
Williams, who was constantly threatening, cut three points from the penalty spot in the 56th minute.
If Atletico can beat Getafe on Monday, they will be fourth in the table, but Real Betis in fifth place will be able to close the gap by one point. Runners-up are still eighth.
Atletico had a brilliant start in the eighth minute when Hamoso crossed William's cross after striking Jose Gimenez.
Williams soon came close to scoring himself, but the 27-year-old's cross from the left corner missed everyone and bounced off Oblak's left post.
Geoffrey Kondogbia was soon woken up by Atletico when they awoke from their slumber and saw Yannick Carrasco rush past Unai Simon's upright effort.
Antoine Griezmann thrashed a free-kick from the crossbar, shortly after which Atletico doubled their lead, with Williams eliminating Iker Muniain from the area and passing with a midfield lead.
Obia ဆက်တိုက် has repeatedly denied Muniain and Nico Williams a move for Atletico, but Angel Correa has been left unlucky for Atletico.
