Liverpool will be looking to put the disappointment of missing out on Champions League football behind them by going for glory in the Europa League.
The Reds have a score to settle in UEFA's second-tier club competition after losing the final the last time they were involved in Jurgen Klopp's first season at the helm. His side were beaten 3-1 by Sevilla in the 2015/16 showpiece but have since gone from strength to strength with remarkable success along the way.
West Ham are also back in the competition after sealing their place thanks to their triumph in the Europa Conference League back in June. The Hammers followed Roma to win UEFA's third-tier competition to automatically qualify after Jarrod Bowen's late goal sealed a narrow win over Fiorentina.
David Moyes' side reached the semi-finals of the Europa League two seasons ago and will now hope to go one better after their exploit in Europe last term. Meanwhile Brighton will be involved in European competition for the first time in the club's history after Roberto De Zerbi steered them to a sixth-place finish in the Premier League last season.
Here's the full schedule for the 2023/24 group stage campaign including confirmed dates and kick-off times (CET).
