Brighton maintained their pursuit of European football with a narrow Premier League win over struggling rivals Crystal Palace.
Solly March's goal proved decisive for the Seagulls and punished a Palace side who spurned three good chances to take control of the game in the opening 10 minutes.
While Wilfried Zaha, Odsonne Edouard and Michael Olise were unable to make the breakthrough for the Eagles, March delivered a clinical finish into the bottom left corner from Kaoru Mitoma's incisive pass.
Roberto de Zerbi's side always looked the more accomplished after that and move level on 42 points with sixth-placed Liverpool, while they are six behind Tottenham in fourth, with two games in hand.
The result will only deepen concerns at Palace of a relegation battle after a dismal 11-game sequence without a win that leaves them 12th but just three points above the bottom three.
De Zerbi later said: "In the first 15 minutes it was very difficult. We had prepared the game in different tactical positions. After 20 minutes we played our game.
"We had the possibilities to close the game and then if you don't the last part was very difficult.
"It is a very good moment [for Solly March] him and the team and no we have to prepare for the next game and a very important next step for Brighton and our mentality.
"The most important thing is the fans understood our style of play and in England this is a great challenge. The players believe in our style. We didn't play our best game but if you win it is better."
