Potter was appointed head coach of Premier League club Brighton &amp; Hove Albion on 20 May 2019, signing a four-year contract. Brighton were victorious in Potter's first match, defeating Watford in a 3–0 away victory in what was also his first game in charge of a Premier League side. Potter's first official home game in charge of Brighton came on 17 August against West Ham where a Leandro Trossard goal was correctly ruled out for offside by VAR which denied Brighton the lead. However, he later went on to score an equaliser to make it 1–1 shortly after Javier Hernández put West Ham a goal up. His first defeat in the Premier League came on 24 August coming at Falmer Stadium against south coast rivals, Southampton where they lost 2–0 with Florin Andone receiving a straight red card for a poorly judged tackle on Yan Valery. His second win as Brighton manager came at Bristol Rovers where they won 2–1 in the EFL Cup. They went on to lose in the next round on 25 September, losing 3–1 at home to Aston Villa where Potter gave 10 Brighton players their debuts in the youthful side of an average age of just over 21. Without a league win since the opening game of season Brighton were starting to drop down the table sitting in 16th after 7 games. On 5 October, after a 6 game winless run Brighton claimed a 3–0 home win over Tottenham Hotspur where Aaron Connolly – who has benefited in game time under Potter – scored 2 goals in his first ever Premier League start. Brighton went on to have a streak of 3 league defeats in November losing to Manchester United, Leicester City and Liverpool but went on to beat Arsenal 2–1 away from home to end the poor run on 5 December. After leading "The Swans" to a quarter final place in the FA Cup the previous season he led "The Seagulls" to a immediate exit from the competition in a 1–0 home defeat against Sheffield Wednesday on 4 January 2020.
