Chris Mepham has been named in Ryan Giggs' 25-man squad for Wales's Nations League games against Republic of Ireland and Denmark early next month.
With Henrik Dalsgaard and Alan Judge also receiving call-ups for their respective nations, it means all three teams in Group B4 currently have Brentford representation for the inaugural round of matches.
Wales begin their campaign with a game in Cardiff against Martin O'Neill's Republic of Ireland on Thursday 6 September, kick-off 7.45pm, before heading to Aarhus three days later for a meeting with The Danes, kick-off 5pm.
The 20-year-old made his international debut for Ryan Giggs' side against Uruguay in March before helping Wales keep a clean sheet against Mexico on his full debut in May. Chris has played every minute in the Sky Bet Championship for Brentford so far this campaign, and featured in both Carabao Cup ties for Dean Smith's side.
The new Nations League concept sees all 55 UEFA member nations divided into four leagues, based on their World ranking, and then divided again into four groups within each league. There's promotion and relegation within each league, as well as an overall Nations League trophy finals next Summer. Countries can also qualify for the 2020 European Championships via the Nations League.
