World Cup 2018: All you need to know about quarter-finals

Seven-goal classics, unbelievable comebacks and England winning a penalty shootout – one of the best World Cups of recent times enters the quarter-final stage on Friday.

BBC Sport looks at the major storylines we can look forward to as we reach the last eight – including the man who loves Uruguay but now has to try to knock them out.

‘The very Uruguayan Frenchman looking to knock his pals out’

There will be an interesting clash between France forward Antoine Griezmann and Uruguay defenders Diego Godin and Jose Gimenez, his Atletico Madrid team-mates. They are such good friends that Godin is the godfather of Griezmann’s daughter.

Griezmann met Godin and Gimenez at Madrid airport wearing a Uruguay jersey when they flew back after clinching World Cup qualification – and has said he feels “part Uruguayan”.

“It’s a nationality that I love, a country that I love and it’s going to be very emotional for me.”

Uruguay midfielder Nahitan Nandez, who used to play for Penarol – a team Griezmann is a member of – said: “Griezmann is very Uruguayan, he passes himself off as a Uruguayan. For him, it’s going to be a special game, like for us.

“All I can say is that we hope he behaves well on the pitch and remembers he is half Uruguayan!”

However, Uruguay’s Barcelona striker Luis Suarez had less time for such sentiment. “He is French and he doesn’t know what it is to feel Uruguayan,” said the 31-year-old.

“He doesn’t know who we are or what we must do to be successful in football. He enjoys our customs and can speak the same language – but we feel differently.”

Atletico Madrid love-in aside, the game itself promises to be a fascinating encounter. Both countries have some of the world’s top attacking talent and knocked out two of football’s all-time greats in the previous round.

France’s squad will have three of the five most expensive players in football, once Kylian Mbappe’s 180m euros (£159m) transfer from Monaco to Paris St-Germain happens. Mbappe became the first teenager since Brazil great Pele to score twice in a World Cup game when France beat Lionel Messi’s Argentina 4-3 in a last-16 epic.

Uruguay – who got past Cristiano Ronaldo and Portugal – have Suarez and Paris St-Germain’s all-time top scorer Edinson Cavani up front. The pair have a combined 98 international goals.
