Club career
Youth career
Mannion joined
AFC Wimbledon at the age of 16.
He was a key member of the Under-18 team that knocked
Premier League academies Watford and Newcastle United out of the FA Youth Cup before a fifth round defeat to Chelsea.
Hull City
In July 2016, Mannion signed for
Premier League club Hull City on a three-year deal.
Due to his age,
AFC Wimbledon were entitled to a compensation fee settled by a
tribunal. In May 2017, it was announced that Hull City would pay an initial fee of £100,000, plus further payments of up to £100,000 for appearances for the first team, and up to £225,000 should he become an Under-21 and full international in a competitive match.
Mannion spent his first season with the club's Under-23 side, and was named on the bench in the EFL Cup in August 2016.
On 1 March 2019, Mannion had his contract with Hull City extended by one-year.
Following the relegation of Hull City at the end of the 2019–20 season to the EFL League One, Mannion was released by the club.
Plymouth Argyle (loan)
Mannion joined Plymouth Argyle on an emergency loan, on the same date of an
EFL Trophy game away to Yeovil Town.
This game quickly became his debut, the game ended in defeat for Argyle as they went crashing out of the cup 2–1 due to a late goal by
Sam Surridge.
This turned out to be Mannion's only game for Argyle.
Aldershot Town (loan)
On 9 August 2018, Mannion agreed to join National League side Aldershot Town on loan until January 2019.
This was later extended to the end of the 2018–19 season.

He was called up to the England Under-19 squad later that year, and made his international debut in a 1–1 draw with Netherlands Under-19s on 1 September.
He made his second appearance a month later in a 2–1 win over Hungary Under-19s.
