Mainland authorities on Saturday said they had launched an investigation into former national football coach Li Tie, with the ex-Premier League player suspected of "serious violations of the law".

A statement on the website of a provincial government said Li was being probed by a disciplinary arm within the General Administration of Sport, but did not specify his alleged offences.

One of China's most recognisable footballers, the 45-year-old played for Premier League side Everton between 2002 and 2006 and made more than 90 appearances for his country.

Li took charge as the national team's head coach in 2020 but stepped down last year. (AFP)
