Barcelona won 3-1 at home against Celta (11th) on Tuesday, with a brace from Aubameyang, at the start of matchday 36 of the League to continue defending its second place in the championship standings.
Barça took the lead with goals from Memphis Depay (30) and Pierre-Emerick Aubameyang (41, 48), but Iago Aspas made up the result (50) for Celta who had nothing at stake in this match.
With the Champions League spot already assured, the Catalans are looking to clinch second place in the standings, which would allow them to play in the Spanish Super Cup next season.
The azulgranas imposed their punch in a game in which they began to suffer against Celta, who disputed possession of the ball, but ended up with ten due to the expulsion of Jeison Murillo (58).
The match was also disrupted by the evacuation by ambulance of Ronal Araujo after suffering a blow to the head and a concussion while trying to head a ball with his teammate Gavi.
Earlier, Granada (16th) beat Athletic Bilbao (8th) 1-0 at home, taking another step away from the relegation zone.
The Andalusian team, which marked the salvation at the beginning of this date, surpassed Cádiz (17th) thanks to the goal by Alex Collado (35th), putting itself five points behind relegation.
Athletic, who have a difficult time reaching the Europa League positions, dominated a Granada in the second half that ended up confined to their field, but managed to keep the score in their favour.
Before, Betis (5th) won 3-0 at Valencia (10th) with goals from Willian José (58), Sergio Canales (87) and Borja Iglesias (89).
Betis, which was placed with 61 points three away from the Champions zone marked by Atlético de Madrid, will need a stumble from the rojiblancos on Wednesday against Elche to continue maintaining their chances of reaching the Champions zone.
The punch of Betis resolved a game that was animated only after the first goal of the Andalusians when Valencia went forward in search of the tie without luck.
