German referee Daniel Siebert was in the studio at MagentaTV and spoke extensively about his decisions in the decisive World Cup match Ghana-Uruguay. According to him, all his three decisions in critical penalty area situations have been assessed as correct by FIFA.
Min. 16: Penalty for Ghana after goalkeeper fouled Kudus. The referee team was too focused on a possible line of sight offside and therefore not concentrated enough on the following challenge. Penalty after on-field review was correct.
Min. 57: No penalty for Uruguay after a challenge between Amartey and Darwin. On-field review was done because VAR Dankert initially failed to see Amartey playing the ball. VAR changed his opinion after Siebert's observation and apologized.
Min. 90+3: No penalty for Uruguay after a duel between Seidu and Cavani. Correct, because Cavani slowed the pace and put his right leg into Seidu's path to "provoke" contact (the ball went left). The same decision (no penalty kick) was previously taken in two similar cases (Qatar-Senegal and Belgium-Canada), hence the expectation of FIFA not to whistle here as well, in the sense of a uniform interpretation of the rules.
