Brighton boosted their Premier League survival bid by completing the double over West Ham with a 3-1 victory at the Amex Stadium
Sensational second-half goals from Jose Izquierdo (59) and Pascal Gross (75) clinched a vital three points for Chris Hughton's men after Javier Hernandez (30) cancelled out Glenn Murray's (7) opener
The result lifts Brighton up to 13th in the table, level on points and goal difference with 12th-placed West Ham, who they trail only by goals scored
After a bruising opening few minutes, during which Gaetan Bong and Aaron Cresswell were injured in aerial duels, Brighton capped their positive start with the opening goal
Referee Roger East played a brilliant advantage after Cresswell scythed Knockaert down, and Pascal Gross released Murray who slotted his 10th goal of the season
Having dusted himself down, Knockaert nearly doubled Brighton's lead on the quarter-hour mark but he sliced wide from Bong's cross
 It took West Ham until the 25th minute to register their first attempt on goal as Sam Byram's header was scrambled off the line by Shane Duffy
Brighton's appeal for a penalty fell on deaf two minutes later despite Knockaert's goal-bound shot striking Angelo Ogbonna's arm - and, to add insult to injury, West Ham were soon level
Having started the attack, Hernandez skipped around three Brighton defenders and rifled an unstoppable drive into the top corner to haul the Hammers level on the half-hour mark
Knockaert failed to convert two chances to restore Brighton's lead before Byram headed over as the Hammers ended the half strongly
West Ham started the second period as tamely as they had the first, though, and it wasn't long until Brighton converted their dominance through Izquierdo's unstoppable drive - his third Premier League goal of the season
And there was to be no way back for the Hammers this time as Brighton added a crucial third in similarly spectacular fashion, Gross jinking inside Ogbonna to seal the victory with a rasping drive
 "In terms of end product, that was the most satisfying performance we've had at home this season
 It was maybe as good as we've been with regards to threatening and looking like we could get more goals
""We never got to the pitch of the game, Brighton were right at it from that start, started much better than us
 We grew into the game, had a few chances before half-time but we never got to the level of the game all day
"On an afternoon when Brighton's attacking players proved too hot to handle for West Ham, it was the Colombia international's stunning second-half strike which will live long in the memory
With just two league goals to his name beforehand, the Hammers will have been forgiven for affording Izquierdo so much space midway through the second half, but he punished them with a clinical finish
 West Ham were on the ropes when the strike flashed into the top corner, and it ensured there was no way back for the visitors
Brighton travel to relegation rivals Stoke and West Ham host Watford next Saturday
