Brighton boss Graham Potter is not sure whether defender Lewis Dunk deserved a red card against Manchester United.
The Albion were beaten 2-0 by the Red Devils, despite dominating the game in the first-half at Old Trafford.
Dunk brought down Anthony Elanga as the last man, minutes after United had taken the lead through Cristiano Ronaldo.
Asked about the incident, which required a VAR review, Potter said per BBC: "It was a yellow card to start with, when I looked at it back it does not look a clear and obvious error.
"That is my feeling. Adam Webster is on the cover and the referee gave a yellow card live. I could have taken it if it was a red card, I don't understand why the VAR is getting involved."
