Born in Chichester, West Sussex, Webster began his career just across the Hampshire border with Portsmouth.

He was handed his Pompey debut by Michael Appleton in a Championship match against West Ham United in January 2012.

In a bid to gain regular first-team football, he joined nearby Aldershot on loan for the first half of the 2013/14 season, before returning to Fratton Park for the closing stages of the season, scoring his first senior goal in a 1-0 win over Hartlepool United.

He moved onto to Ipswich Town in 2016, with defender Matt Clarke - who would be signed by Albion later on in his career - moving in the opposite direction as part of the deal, and spent two years with Suffolk side before joining Bristol City in 2018.

He played 47 times in his one season at City, scoring three goals.

In total, Webster has made more than 300 senior appearances and has represented England at under-18 and under-19 level.

He was a regular during his first season with Albion, making 31 Premier League appearances, scoring his first goal for the club against Aston Villa.

The defender impressed in his second year at The Amex, forming a strong partnership with Lewis Dunk and Ben White in a back-three for Albion. He would go onto make 29 Premier League appearances in the 2020/21 season, and would have no doubt made more were it not for an ankle injury in the second part of the campaign.

He signed a new five-year contract with Albion in August 2021.

Adam made his 100th Albion appearances in October 2022, in a 3-1 defeat at Manchester City.
