Dwight McNeil returned to the Clarets' camp with two England caps to his name.
McNeil, 19, followed up his full international debut for the U20s in a 3-1 Euro Elite League defeat at home to Poland with an appearance from the bench in a 1-0 loss in Portugal.
And that capped an eventful first call-up for the winger, who also trained with the senior squad at St George’s Park.
Youth team Player of the Pear McNeil, who only made his Clarets debut in May, 2018, has since gone on to start the last 13 Premier League games for the club, played in European competition and scored his first senior goal.
Elsewhere during the international break, Jeff Henrick and Robbie Brady both starred for Ireland as they started their European Championship qualifying campaign with back-to-back wins.
Midfielder Hendrick scored the only goal as Ireland started a new era under Mick McCarthy with a slender 1-0 win in Gibraltar, and he was then joined in the starting line-up by team mate Brady as Ireland saw off Georgia 1-0 in Dublin to pick up maximum points.
Defender Kevin Long, the club’s third member of the Irish contingent, was an unused substitute in both games.
England duo Tom Heaton and James Tarkowski were part of the England squad that also picked up two wins against the Czech Republic and Montenegro and at the start of their Euro 2020 qualifying group.
Neither added to their international caps, although there was a Burnley presence at Wembley Stadium as Czech striker Matej Vydra made an appearance as a second half substitute in England’s 5-0 victory.
Vydra added to his caps with another substitute appearance in Tuesday’s 1-3 friendly defeat to Brazil in Prague.
Johann Berg Gudmundsson was also in action as Iceland had a mixed start to qualifying, following up a 2-0 win in Andorra, in which the Clarets winger played 83 minutes, with a 4-0 defeat to France in Paris that Gudmundsson sat out.
