The Champions League semi-final second leg between Arsenal and Atletico Madrid was not without its share of controversial refereeing decisions. The Gunners secured a 1-0 victory to advance to the final, but referee Daniel Siebert failed to award Atletico a penalty in the second half after Antoine Griezmann was fouled by Ricardo Calafiori inside the box.
AS's refereeing analyst, Iturralde González, was adamant that Siebert should have pointed to the spot.
"He steps on him, that's a penalty. He hits his standing leg and brings him down," commented Iturralde González.
However, Siebert had called a foul on Marc Pubill against Gabriel Magalhães a second earlier, a decision Iturralde González also disagreed with.
"That's the key moment – whether he blew the whistle for the foul before. But if he didn't call it, it's a VAR situation. VAR could have called him over to review the foul," stated the former international referee.
"If Pubill had hit him, Gabriel's leg would have moved, but what the defender does is pull his leg back to avoid committing a foul," Iturralde González explained the situation.
He added that the German referee correctly did not award a penalty when Giuliano Simeone claimed he was brought down by Gabriel Magalhães.
A similar incident occurred before halftime, but in Atletico's penalty area. Griezmann challenged Leandro Trossard, who appealed for a penalty, but Iturralde González believes the contact was minimal and the referee was right to wave play on.
