West Ham boss David Moyes said the video assistant referee is making "terrible decisions" in the Premier League, despite seeing his side fight back to beat Leeds and move up to fifth.
Leeds had gone in front when Mateusz Klich converted a twice-taken sixth-minute penalty, with VAR ordering the retake after ruling keeper Lukasz Fabianski had stepped off his goalline.
However, the visitors - who had won just once on the previous 26 occasions when they had conceded first in a Premier League game - levelled when Illan Meslier failed to stop Tomas Soucek's soft header and won it with 10 minutes to go through Angelo Ogbonna's header.
