Luton were handed a heavy defeat in their first Premier League game in 31 year, losing 4-1 to Brighton.
Joao Pedro and Simon Adingra marked their debuts with a goal each in a comfortable Brighton win.
Solly March headed in after 35 minutes before Pedro, signed for a club-record fee around £30m from Watford, scored a second-half penalty following a foul by Luton captain Tom Lockyer.
Luton pulled a goal back with nine minutes remaining when last season’s top scorer Carlton Morris converted another penalty – awarded for handball against Lewis Dunk – but 21-year-old Ivorian Adingra sealed the Seagulls’ win by slotting home after a bad mistake from Luton’s Pelly Ruddock Mpanzu.
Eighteen-year-old Ireland international Evan Ferguson then tapped in Pervis Estupinan’s cross in stoppage time to cap an impressive start to the campaign for the home side.
