Benjamin James Chilwell (born 21 December 1996) is an English professional footballer who plays as a left-back or left wing-back for Premier League club Crystal Palace, on loan from Chelsea, and the England national team.

[12] Despite only spending six weeks at the West Yorkshire club, Chilwell would later describe his spell as "a big part of [his] growth in [his] career"[13] and credited Huddersfield manager David Wagner with aiding his development as an attacking full back.

[21] He made 19 appearances across the 2016–17 season, including two in the UEFA Champions League, and scored his first career goal on 18 May 2017 in a 6–1 home loss to Tottenham Hotspur.

[27] On 26 August 2020, Chilwell signed a five-year contract with Chelsea, after Leicester City had accepted an offer for the player, reported by BBC Sport to be £45 million.

[28] He made his debut on 23 September, providing the assist for Olivier Giroud's goal in a 6–0 home win against Barnsley in the third round of the EFL Cup after he came off from the bench.

[29] On his first league start for the club on 3 October, Chilwell scored the opening goal and assisted Kurt Zouma for the second as Chelsea beat Crystal Palace 4–0 at home.

[32] On 29 May, Chilwell won his first-ever trophy after Chelsea defeated Manchester City 1–0 in the 2021 UEFA Champions League final in Porto.

[35] On 23 November 2021, Chilwell sustained a ruptured cruciate ligament injury in a 4–0 home win during Chelsea's 2021–22 UEFA Champions League group stage match against Juventus.

[44] Along with his Leicester teammate Demarai Gray, Chilwell was called up from the under-21 team to the full England squad in September 2018 for a friendly match against Switzerland.

[46] Upon taking to the pitch in the match at the King Power Stadium he became the first England player to debut at his club ground since Paul Scholes at Old Trafford in 1997.

[47] Chilwell made his first start on 12 October in a goalless draw with Croatia in the 2018–19 UEFA Nations League A, in a match played behind closed doors.

[7][53] Chilwell's maternal grandfather Guy Shuttleworth was also a sportsman who played football for Corinthian-Casuals — winning an international cap for England Amateurs in 1949 — and represented Cambridge University at first-class cricket.
