The highly rated 21-year-old, who has been with City’s Academy since the age of eight, made his senior debut for the Foxes in a 4-0 Premier League win over Newcastle United in December 2021.
He has gone on to appear for the Foxes on three further occasions, including twice this term, in victories over Gillingham in the Emirates FA Cup and MK Dons in the Carabao Cup.
McAteer spent the second half of 2021/22 on loan in League 2 with Forest Green Rovers, where he made nine appearances and helped the club earn promotion to League 1 as champions.
McAteer then spent the second half of 2022/23 out on loan at AFC Wimbledon in Sky Bet League 2. He furthered his football education with the Dons, who finished in 21st position in the fourth tier, before a landmark moment back at Leicester.
Now under Enzo Maresca's management, the Foxes started the 2023/24 season at home against Coventry City - with McAteer impressing in the Sky Bet Championship opener at right wing. Despite injury, he was back in the XI for a visit to Rotherham United later in the month and he scored both goals in a 2-1 win to send the Foxes top of the table.
He was on the scoresheet again a few weeks later, netting in a 4-1 win at Southampton, later also scoring in a 2-0 success at Norwich City the following week.
