Reece Oxford
Oxford made his competitive, first team debut on 2 July 2015, aged 16, starting in midfield in a 3–0 win against Andorran club Lusitanos in a UEFA Europa League first qualifying round first leg draw. In so doing, he became West Ham's youngest ever player. He then made his Premier League debut on 9 August, playing the first 79 minutes before being substituted for Kevin Nolan as West Ham won 2–0 away to Arsenal. Following his start, Oxford became the second-youngest Premier League starter of all-time, after Jose Baxter.
