West Ham boss David Moyes has held talks with referees' chief Howard Webb about the VAR controversy in their midweek 2-1 Premier League defeat by Liverpool.
Moyes accused the VAR of 'disrespect' after West Ham were denied a late penalty when Thiago's arm hit the ball as he challenged Danny Ings in the box.
The Hammers boss was convinced VAR Neil Swarbrick should have at least told on-field referee Chris Kavanagh to review the incident on the pitchside monitor.
But, speaking on Friday, Moyes refused to divulge whether he had received an apology from the PGMOL.
