The World Cup draw was made in Russia on Friday, with all eyes on what the so-called group of death would be.

Here, Press Association Sport takes a look at which of the eight groups looks the most difficult.

Group F

Germany

Nobody would have wanted to be paired with the reigning champions, who have not lost a game since the semi-finals of Euro 2016. While the likes of captain Philipp Lahm, record World Cup goalscorer Miroslav Klose and influential midfielder Bastian Schweinsteiger have moved on from the team of four years ago, they remain the squad to beat. They retain the likes of Toni Kroos, Mesut Ozil and Thomas Muller and have added exciting youngsters Leroy Sane, Timo Werner and Leon Goretzka, who helped an inexperienced Germany squad win the Confederations Cup last summer.

Mexico

Mexico qualified comfortably in a CONCACAF section that proved too difficult for the United States. Juan Carlos Osorio's side lost just one of their 10 games in the final group, finishing five points clear of second-placed Costa Rica. And they have the pedigree to get through the groups in Russia. They have reached the second round at the last six tournaments, though they have failed to go any further since they hosted the finals in 1986. Record goalscorer Javier Hernandez will hope to score at a third successive tournament, while exciting young winger Hirving Lozano can make a name for himself.

Sweden

The team that knocked Italy out of the qualifying play-offs will have their eyes on another major scalp. Sweden finished ahead of 2014 finalists Holland in their qualifying group, then kept the four-time winners scoreless in a two-legged play-off. Manager Janne Andersson has made the Scandinavians well organised and tough to beat, while RB Leipzig winger Emil Forsberg ensures they carry a threat on the break. Sweden finished third in 1994 and progressed through their group on each of the last two occasions they qualified (2002 and 2006). And there is also the chance that Zlatan Ibrahimovic comes out of international retirement for a World Cup swansong.

South Korea

They are no longer the threat they were when they reached the third place play-off on home soil in 2002, but they remain one of the strongest teams in Asia. Two years ago they were denied their first Asia Cup since 1960 when they lost to Australia in extra-time of the final. They stuttered through qualifying, winning just four of their 10 games in the final round to pip Syria by two points, while finishing seven points behind Iran. But Tottenham star Son Heung-min will cause every defence problems and if South Korea can keep them out at the other end, they can cause a surprise or two in Russia.
