Four-time winners Germany arrived at the World Cup in Qatar on Thursday while Iran's captain urged his team to focus on football rather than anti-government protests that have rocked his country.
With just three days remaining before the month-long tournament kicks off, teams are still arriving in Qatar after completing last-minute preparations for the event.
Germany were the most prominent team to touch down in Doha on Thursday, fresh from a 1-0 friendly victory over Oman on Wednesday.
The 2014 champions are aiming to erase the memory of their ill-fated campaign in Russia four years ago, when they crashed out of the World Cup in the group stage.
Unlike most of the 32 teams at the tournament who have opted to be based in and around Doha, Germany have opted to be based far from the Qatari capital.
Team official Oliver Bierhoff explained why they had chosen the seaside town of Al-Ruwais, 68 miles (111 kilometers) from Doha.
"We want to develop a team spirit there that will carry us through the tournament - and for as long as possible," Bierhoff said.
Spain are due to arrive in Qatar in the early hours of Friday while France arrived in Doha late Wednesday, seeking to become the first team to retain the World Cup since Brazil in 1962. Argentina and Lionel Messi were also settling into their accommodation.
Iran's team arrived in Qatar with their homeland rocked by anti-government protests that have cost the lives of dozens of people and become the regime's biggest challenge from the street in decades.
Iran captain Alireza Jahanbakhsh, asked by a British journalist if his team was able to concentrate on their first match against England on Monday, said: "We are here to play football and that's the main thing everybody is focused on while we're here.
"To bring it this way to play the mental game and ask what's going on here, there or whatever. We are just four days away from playing the biggest games of our lives."
On whether the players would join other Iranian sports figures who have refused to celebrate victories as a form of support for the protests, he said: "You talk about celebration; celebration is something very personal.
"Every single player has a different celebration and you ask about national anthem and that's something that also has to be decided in the team which we already talked about."
