Benfica head to Brazil this weekend for a friendly with Santos, while around half of the first-team squad are away on international duty. Read on to discover which players have been selected by their respective countries.

Fernando Santos did not include a single Benfica player in his original squad, but has called up Nélson Semedo and Pizzi to replace the injured Cédric Soares and Nani, respectively. The European Champions take on Andorra on Friday 7th October and the Faroe Islands on Monday 10th October. Pizzi has not featured for Portugal since appearing in a friendly against Italy in June 2015.

André Horta, João Carvalho and Gonçalo Guedes were all named in Rui Jorge's latest squad, although Horta was forced to withdraw through injury. He has been replaced by Benfica B midfielder Pedro "Pêpê" Rodrigues. João Teixeira, on loan at Wolves, also made the cut. Portugal's opponents are Hungary on Thursday 6th October, and Lichtenstein on Tuesday 11th October.

Seven Benfica players will participate in a five-day training camp in Rio Maior this week. Coach Emílio Peixe will be joined by Aurélio Buta, Diogo Gonçalves, Francisco Ferreira, Heriberto Tavares, Pedro Amaral, Ruben Dias and Yuri Ribeiro (pictured below). Pedro Rodrigues was also selected, but was subsequently promoted to the under-21 squad. Gonçalves, Dias and Ribeiro will leave the camp early to feature in Benfica's friendly with Santos this weekend.

Portugal's under-19s have back-to-back friendlies against Italy on Thursday 6th October and Sunday 9th October. Five Benfica players were included in Hélio Sousa's initial squad: Fábio Duarte, Florentino, Gedson Fernandes, José Gomes and Tiago Dias. After the first game, José Gomes will be released to join the Benfica first-team in Brazil.

Kostas Mitroglou
will earn his 50th international cap on his next appearance for Greece. He has two opportunities to do so in the coming days, with games against Cyprus on Friday 7th October and Estonia on Monday 10th October. Andreas Samaris was unavailable for selection due to injury.

Pawel Dawidowicz
, on loan at German side Bochum, could earn his second senior cap for his native Poland, who play Denmark on Saturday 8th October, and Armenia on Tuesday 11th October.

Victor Lindelöf
has already been in the headlines this week, with his former club, Västerås SK, accusing Benfica of neglecting to pay a performance-related bonus payment. The player himself will be focusing on Sweden's games with Luxembourg, on Friday 7th October, and Bulgaria, on Monday 10th October.

Ljubomir Fejsa will be looking to add to his 22 caps for Serbia, who face Moldova on Thursday 6th October and Austria on Sunday 9th October.

Andrija Živković
, fresh from his competitive debut for Benfica last weekend, has joined up with Serbia's under-21 squad. They meet the Republic of Ireland on Friday 7th October, and Slovenia on Tuesday 11th October.

Álex Grimaldo has made the left-back berth his own at Benfica, and he will now try to do the same with Spain's under-21s, who play San Marino on Wednesday 5th October, and Estonia on Monday 10th October.

Jhon Murillo will hope to build on his impressive recent form for Tondela, to whom he is on loan from Benfica. Venezuela do battle with Uruguay on Thursday 6th October, and Brazil on Tuesday 11th October.
