The Swans will have 17 players representing their respective countries during the international break.

Five of them come at senior level, with Lukasz Fabianski, Jordan Ayew, Ki Sung-Yueng, Martin Olsson and Kristoffer Nordfeldt all in action.

Fabianski could play a big part as Poland look to close in on qualification for the World Cup with matches against Denmark and Kazakhstan.

The Group E leaders sit six points clear at the top from Montenegro and Denmark, with the latter providing the opposition on Friday.

Poland then host bottom team Kazakhstan in Warsaw on Monday knowing two victories would move them even closer towards securing their place at the World Cup in Russia.

Swedish duo Olsson and Nordfeldt face two away matches as they look to cement their place at the top of Group A.

First up is Thursday’s clash in Sofia with Bulgaria before Sweden travel to Borisov to take on Belarus on Sunday.

Ayew is also on World Cup qualification duty with Ghana, who face a double-header against Congo.

Ghana are third in Group E in the African qualifying section knowing they must put pressure on leaders Egypt, who sit top having won both of their two games so far.

Ki Sung-Yueng has linked up with South Korea as they play two key matches in their Asian qualifying group.

Ki is yet to feature for the Swans this season having undergone knee surgery while on international duty in the summer.

The South Korea captain has been called up by manager Shin Tae-Yong, although he is not expected to feature, in order to have a positive influence on the squad ahead of their crucial matches against leaders Iraq and Uzbekistan.

Two victories would confirm their qualification for the World Cup with a second-placed finish in Group A.

The Swans have seven players in action at under-21 level.

Tammy Abraham, who scored his first Premier League goal for the Swans in last weekend’s 2-0 win at Crystal Palace, is part of England U21s’ squad for the games against Holland and Latvia.

Oli McBurnie, meanwhile, will also go up against Holland as he has been called up by Scotland U21s.

Jack Evans, Joe Rodon, Cian Harries and Daniel James - who is on loan at Shrewsbury Town - are part of Wales U21s’ squad for the forthcoming matches against Switzerland and Portugal.

Marco Dulca will represent Romania U21s as they travel to Bosnia Herzegovina before hosting Switzerland.

Finally, Brandon Cooper, Joe Lewis, Mason Jones-Thomas, Kieran Evans and Liam Cullen will also be on national duty as they form part of Wales U19s’ squad as they take on Iceland in back-to-back games in Rhyl.
