Wales captain Ashley Williams has announced his retirement from professional football.

Williams, 36, has been without a club since being released by Bristol City at the end of last season.

He won 86 caps for Wales, leading them to the semi-finals of Euro 2016.

The former Swansea City and Everton centre-back announced his decision on social media, describing his career as an "incredible journey" having represented some "incredible teams".

He captained Wales to only their second ever major tournament at Euro 2016 and, announcing his retirement on Tuesday, he described being captain as they reached the last four in France as "my greatest achievement and something I will never forget".

Williams added: "Football has taught me so much both on and off the field and I will take this with me into the next chapter.

"I look forward to still being involved in the game in the future."
