Delap joined Derby County's academy at the age of six where he spent the next 10 years before joining Manchester City's academy in 2019, impressing from a young age and being capped at several youth levels with England.[10] He scored a goal and set up two others in the final of the 2020 Under-18 Premier League Cup.[11]
On 24 September 2020, Delap made his first-team debut in a 2–1 home win against AFC Bournemouth in the EFL Cup, scoring his first senior goal in the 18th minute.[12] After the match, manager Pep Guardiola praised him and confirmed Delap would continue training with the first team.[13] Three days later, he made his Premier League debut in a 5–2 home defeat by Leicester City, coming on as a substitute for Fernandinho in the 51st minute.[14] In April 2021, Guardiola confirmed that Delap would be moved up to the first team permanently before the following season.[15] Delap won his first trophy on 25 April, when City defeated Tottenham 1–0 in the League Cup final at Wembley Stadium.[16] Delap, however, was not selected for the squad and instead had to follow the match from the stands.[17]
During the 2021 pre-season, Delap suffered an injury to his foot, which led to him missing the Community Shield against Leicester City, which Manchester City lost 1–0, and the 2021–22 Premier League opener against Tottenham Hotspur, which they also lost 1–0. On 20 August, amid interest from several Championship clubs looking to loan him, Delap signed a three-year contract extension, keeping him at the club until 2026.[18] Following a number of injuries, he made his first appearance of the season as a substitute in the FA Cup Third Round tie against Fulham in February 2022,[19] and also came on during the 4–0 win over Norwich City in the Premier League, winning the penalty for the fourth goal.[20] On 15 February 2022, Delap made his UEFA Champions League debut in the first leg of the round of 16 tie as a substitute for Bernardo Silva, in a 5–0 away win over Primeira Liga champions Sporting CP.[21]
On 18 August 2022, Delap joined Stoke City on loan for the 2022–23 season.[22] He scored his first goal for Stoke in a 3–1 win over Sheffield United on 8 October 2022.[23] After making 23 appearances for Stoke, scoring three goals, Delap was recalled by Manchester City on 12 January 2023 and was sent to Preston North End for the remainder of the 2022–23 season.[24][25]
On 2 July 2023, Delap joined Hull City on a season long loan.[26] He made his debut on 5 August 2023 in the 2–1 loss away to Norwich City, scoring the opening goal of the match.[27] Delap was named Hull City's Player of the Month for December 2023.[28]
