Manchester United fans have been reacting following Brighton defender Lewis Dunk's sending off.
After a poor first half where the Seagulls had the better of the chances and the possession, United came out looking far better in the second period.
Just after the break, Cristiano Ronaldo broke his goal drought to give the home side the lead.
Only three minutes later things went from bad to worse for the visitors. As youngster Anthony Elanga burst forward for the hosts, centre-back Dunk dragged the 19-year-old to the ground.
Initially, referee Peter Bankes showed the Brighton man a yellow card, though a check of the pitchside monitor saw the yellow upgraded to a red.
