BURNLEY duo Sam Vokes and Steven Defour have been called up by their national sides ahead of their upcoming World Cup qualifiers.

Vokes started the season in fine form, scoring twice on the opening day in the 3-2 win at Chelsea, which made it seven goals in his last six Premier League outings.

Defour meanwhile has also enjoyed something of a revival in a Clarets shirt, starting the opening two Premier League games, and is in the Belgium squad for qualifiers against Gibraltar and Greece.

Twenty-seven-year-old Vokes is one of six forwards included in Chris Coleman’s 25-man squad ahead of qualifiers against Austria and Moldova.

Vokes has 50 caps for his country, the latest of which came in a 1-1 draw in Serbia in June, and has scored eight goals.

Wales, who welcome back Gareth Bale from suspension, are third in Group D, four points behind Serbia and Republic of Ireland who are first and second respectively.

They host Austria on September 2, and then travel to Moldova three days later, in need of points with only the group winners certain of a place at the 2018 World Cup in Russia, while the eight runners-up with the most points will qualify for the play-offs.

Defour hasn’t featured for his country since a 6-0 win in Gibraltar in October, but his fine form for Burnley has seen him recalled by Roberto Martinez.

The 29-year-old has 51 caps for his country who are currently top of Group H with five wins and a draw from their six games.

They will make certain of their place in Russia if they can record wins over Gibraltar on August 31 and then Greece on September 3.
