Knocked out in the quarter-finals in 2014, France have built a hugely impressive squad and will hope to make up for their near-miss on home soil in Euro 2016, when they lost in the final to Portugal. Capable of going all the way.

Peru had not qualified for the World Cup since 1982, but finally booked the last spot in Russia with a 2-0 victory over New Zealand in the second leg of their play-off. Paolo Guerrero's inclusion after initially being banned is a major boost and they are tipped to battle Denmark and Australia for the second qualifying spot in the group behind favourites France.

Defenders: Aldo Corzo, Luis Advincula, Christian Ramos, Miguel Araujo, Alberto Rodriguez, Anderson Santamaria, Miguel Trauco, Nilson Loyola.

World Cup best: Winners 1978, 1986
A nervy qualification campaign saw one of world football's great powers book their place at the last opportunity with victory over Ecuador, but the losing finalists in 2014 will be looking to go one better. That said, the Lionel Messi-less side's 6-1 loss to Spain in March suggests that is a big ask.
Goalkeepers: Nahuel Guzman, Willy Caballero, Franco Armani.
Defenders: Gabriel Mercado, Nicolás Otamendi, Federico Fazio, Marcos Rojo, Marcos Acuña, Cristian Ansaldi, Nicolas Tagliafico.
Midfielders: Javier Mascherano, Ángel Di María, Ever Banega, Lucas Biglia, Manuel Lanzini, Gio Lo Celso, Maximiliano Meza, Eduardo Salvio, Cristian Pavon.

A comfortable qualification campaign did little to boost optimism for England's chances in Russia, although recent promising friendly displays may have. This is a first major tournament in charge for Southgate, who watched from afar as the Three Lions failed to make it out of the group in Brazil. The wounds of the Euro 2016 last-16 exit to Iceland also remain raw.
