Barcelona are expected to file a formal complaint over a handful of controversial decisions in their 4–0 Copa del Rey semifinal first leg battering at Atlético Madrid on Thursday.
After shipping four first-half goals, Barcelona felt as though the officials were their toughest opponents after the interval. Pau Cubarsí saw a 52nd-minute goal ruled out for offside even though semi-automated offside technology was not used, before Atlético’s Giuliano Simeone avoided a red card for a crunching challenge on Alejandro Balde.
