The Premier League has become used to VAR controversy this season and Thursday night was no exception.
Crystal Palace found themselves wronged as two decisions went in favour of Manchester United at Selhurst Park, leading to their chairman Steve Parish asking on Twitter if the technology was broken.
Palace felt they should have been awarded a first-half penalty when Wilfried Zaha was brought to the floor by Victor Lindelof but the VAR officials at Stockley Park thought differently.
And after the break, Jordan Ayew thought he'd equalised for Palace only to be judged offside by the slightest of margins.
