Fabian Hurzeler and Eddie Howe agreed that VAR was right to overturn two Newcastle penalties - but the Brighton boss felt they missed one for his team.
Stockley Park said that Craig Pawson was wrong to give the visitors second-half spot-kicks when Tariq Lamptey tripped Anthony Gordon just outside the area and Joe Willock dived under a challenge from Jan Paul van Hecke.
Pawson got it right when Yasin Ayari handled in the 89th minute and Alexander Isak claimed Newcastle a point from the spot.
But the referee had earlier missed Sandro Tonali’s clumsy kick on Matt O’Riley, as Hurzeler said: ‘The referee blew the whistle when there's not even a touch (Willock dive) and gave a penalty for them.
