According to the match report, sanctioning Romanian referee Ştefan Covaci hinges on his interpretation of the on-pitch incident, which alone may not warrant disciplinary action; the same applies to the VAR’s failure to intervene.
Despite the controversy, it remains to be seen whether the Romanian official, who has previously refereed the finals of all three European club competitions, will be entrusted with any of the semi-final ties in the Champions League, Europa League or Conference League.
Barcelona lost 2-0 at home to Atlético Madrid in the first leg of the Champions League quarter-finals.
Barcelona played with ten men from the 44th minute after Pau Cubarsi was sent off.
The sides will meet again next Tuesday at the Metropolitano Stadium for the second leg.
