Tom Lockyer signed for the club in the 2020 summer transfer window after leaving Charlton Athletic.
Locks joined the Addicks following their promotion to the Sky Bet Championship in 2019 after spending seven years at Bristol Rovers following his release by Cardiff City at the age of 16.
The centre-half helped Rovers win successive promotions from the National League to League One, where he twice came up against the Hatters as Pirates captain in our 2018/19 title-winning campaign.
Locks made his debut for the Hatters in the Carabao Cup against Reading and was included in the Wales squad for Euro 2020 at the end of his first season with us.
He made a further 33 appearances for the Hatters in the 2021/22 season, scoring his first goal for the club against Bristol City - fierce rivals of his former club, Bristol Rovers.
Our number four was part of the 2022 World Cup squad with Wales, before leading us to the Premier League at the end of that season.
