The first international break of the season is upon us and with it an early two-week break from the drama and entertainment of the Premier League.

Much will be said about the shape that Liverpool enter the break - after one win, one draw and one defeat in their first three games of the Premier League campaign - while the mainfocus turns to Sam Allardyce's first game as England manager.

Back on Merseyside, Jürgen Klopp will get the chance to deeper dissect the Reds' first few performances, but while he analyses and scrutinises at Melwood - where will his first-team players be on international duty?

As many as 15 players, including three of the club's seven summer signings, could represent their countries before reuniting to Melwood ahead of a clash with reigning champions Leicester City on September 10.

Four Reds in England squad to face Slovakia 

The largest contingent sees four players included in former Sunderland boss Allardyce's first Three Lions squad. 

Nathaniel Clyne, Jordan Henderson, Adam Lallana and Daniel Sturridge have all been called up. There is no James Milner, who retired international football earlier this month.

England face former Reds centre-back Martin Skrtel and his Slovakia side in a 2018 World Cup qualifier in Trnava on September 4.

Georginio Wijnaldum is in the Netherlands squad managed by Danny Blind's - father of Manchester United's Daley Blind - for their forthcoming fixtures.

The summer signing has yet to settle into a central midfield position in Klopp's eleven, but is likely to continue in the same role for his national team as they host Greece in a friendly on September 1.

Origi and Mignolet in Martinez's first Belgium squad

After that, they kickstart their qualifying campaign for the World Cup - having missed out on the European Championships this summer - away at Sweden on September 6.

With former Everton boss Roberto Martinez now in charge, Simon Mignolet and Divock Origi have both been picked for Belgium.

The pair will hope to try and impress the new boss as they take on Spain in a friendly in Brussels on September 1, before travelling to Cyprus for their opening World Cup qualifier in Nicosia on September 6. 

After missing out on the Euros due to a fall-out with Croatia manager Ante Cacic, centre-back Dejan Lovren has returned to the squad with the pair having cleared the air.

Lovren is in the 23-man squad picked to take on Turkey, whom they beat 1-0 in the group stages of the Euros, in Istanbul on September 5 - though the game will be played behind-closed-doors after FIFA sanctions.

The defender will hope to cement a place as part of the starting eleven under Cacic, having been frozen out after demanding a permanent place in the XI.

Emre Can is once again called up for Joachim Low's reigning World champions as they prepare to face Finland and Norway in a four-day double-header.

Germany host the Finnish in Monchengladbach on August 31, a game dubbed Bastian Schweinsteiger's farewell with the national team captain bringing the curtain down on his international career afterwards.

Four days later, they take on Norway in a first World Cup qualifier - with Can hopeful of building on his tally of seven appearances, the majority of which have come at right-back thus far. 

Elsewhere, Marko Grujic and Lazar Markovic will both hope to be involved as Serbia face Republic of Ireland on September 5 in a World Cup qualifier in Belgrade.

Summer signing Grujic will hope to make just his fourth senior appearance for his country, while Markovic will hope that a lack of minutes at club level doesn't prevent him from featuring for Slavoljub Muslin.

The out-of-favour winger could yet leave Liverpool before the transfer window closes on Wednesday night.

Estonia captain Ragnar Klavan is also involved over the break, with Magnus Pehrsson's team coming up against Malta on August 31 and then Bosnia & Herzegovina on September 6.

Having suffered a minor knee injury which kept him out of Liverpool's clash with Tottenham Hotspur before the break, the experienced centre-back will hope to use the games to return to full fitness.

Coutinho called up for Brazil, but no Firmino

Outside of Europe, Philippe Coutinho has been named in the Brazil squad for their two World Cup qualifiers, although Roberto Firmino hasn't made the 23.

The attacking midfielder features in new manager Tite's first squad as Brazil boss as they face Ecuador in the capital of Quito on September 1 and then Colombia in Manaus on September 7.

Sadio Mane, who has enjoyed a terrific start to his Liverpool career, could feature for Senegal in their African Cup of Nations qualifying clash with Namibia.

However, Joel Matip isn't in the Cameroon squad for their AFCON qualifier with Gabon on September 6 and will remain with the Reds.

Cameroon head coach Hugo Broos explained that he "called [Matip] 15 times" and "made him messages" to which he "never responded" while the defender's brother Marvin Matip "preferred to stay" with his club, Ingolstadt.

Otherwise goalkeeper Danny Ward, who has impressed on loan at Huddersfield Town in the Championship, makes the Wales squad for their qualifier with Moldova on September 5.
