Ethan showcased his talent in his tenure with Leicester U18s in the U18s Premier League, amassing 39 appearances and contributing to 14 goals. This garnered the attention of Brendan Rodgers, earning him a place in the senior side during pre-season at the age of 16. Notably, he trained with former Premier League champions Wes Morgan, Jamie Vardy and Kasper Schmeichel.

On 5th November 2020, Fitzhugh was named on the bench for Leicester City's 4-0 home victory over Braga in the Europa League. Subsequently, he ascended to the Foxes' U21 side. Fitzhugh marked a milestone in December 2021 by scoring his first two goals for the club's development squad, securing a 3-1 triumph over Leeds United Under-21s and clinching the team's inaugural away win of the 2021/22 season.

The subsequent season saw Ethan Fitzhugh become a regular for Ben Petty’s U21 side, playing 14 of their 19 fixtures across all competitions, usually from the right wing. Despite contributing two assists and one goal Ethan faced an unfortunate setback with an ACL injury in January 2023, prematurely concluding his campaign.

A skilful and versatile midfield player who can operate on the wing or in attacking midfield, Fitzhugh brings both solidity and talent into attacking areas for the Banbury United and the signing has delighted the boss, Mark Jones: “Ethan came to our attention through Adi Yussuf’s work with Leicester City’s U21s. He is an exciting attacking midfielder that will hopefully give us the creativity in the final third that we have been searching for.”
