Jonny Williams' career has mirrored a roller coaster but he is determined to enjoy another high with Wales next summer.

The midfielder was unable to stop Charlton going straight back down from the Sky Bet Championship last month – a year after he helped the Addicks into the second tier with promotion via the League One play-offs.

Williams featured in the Wembley win against old club Sunderland in May 2019 after he had spent the 2017-18 campaign on loan with the Black Cats, who went on to suffer relegation.

With injury woes seemingly behind him, the midfielder craves to experience another major tournament.

"After the experience at the Euros, I still get people asking me how it was," Williams revealed.

"It's one of those things you never think you will experience as a footballer, to go to a major tournament.

"To have the opportunity to do it all over again is massive and the main thing is to put myself in a position to go and then it's obviously up to the staff. As long as I am playing and I am fit, I'll have no regrets."
