O'Reilly will join Manchester City teammates James Trafford and John Stones in the England squad for upcoming internationals against Wales and Latvia. This is O'Reilly's first senior international call-up, following previous appearances for England's under-15, under-20, and under-21 teams.
The 20-year-old has had a successful start to the season, making nine appearances in all competitions and helping Manchester City remain undefeated in games where he has started.
Manchester City has released a statement congratulating O'Reilly on his call-up, praising his impressive performance so far this season.
O'Reilly's inclusion in the England squad comes as a boost to manager Thomas Tuchel, who has confidence in the young defender ahead of the international break. Meanwhile, Manchester City is dealing with a shortage of centre-backs, with five players unavailable due to injury, including two who were forced to leave the Liverpool match injured.
O'Reilly's experience representing England at various youth levels will likely serve him well as he joins the senior team for the first time.
