It's not quite on the same scale as at your average Argentina game but the number on the back of all the Croatia shirts in this stadium is the same set of double digits sported by Messi and Maradona.
The name starts with the same initial and, yes, he is a little magician too...

Croatia have lost only two of their eight World Cup knockout games (W4 D2), and they progressed from the two drawn matches on penalties - both in 2018.
Only Germany (8/8), France (6/6 after yesterday) and Croatia (2/2) have played more than one World Cup last 16 tie without being eliminated at this stage.

Croatia manager Zlatko Dalic admitted he did not think they would be playing Japan today when Alvaro Morata put Spain 1-0 up against the Asian side.
"When Spain scored the opening goal, I thought Japan were finished, but they never gave up and deserved their victory," Dalic said.
"The fact that Germany, Belgium and Denmark have all been eliminated illustrates just how strong other teams have been at this World Cup.
"In the past, I might have picked Japan as an opponent that we would want to play, but they have defeated both Germany and Spain. This certainly will not be an easy game for us."

Japan have been an astounding presence in this World Cup.
But the Samurai Blue are taking nothing for granted as they prepare to face Croatia.
"It's another wall they have to break," Japanese sports journalist Kumi Kinohara told me.
"We'll have to keep our fingers crossed. But I want to see them play in their own style."
The Asia Pacific teams have been fearless on the pitch and have given their fans a lot to cheer for. Their performances so far have left some of the football powerhouses like Germany, Spain and Portugal in shock.
This is the
only one of the eight quarter-finals to NOT feature one of the top seven ranked
teams on Gracenote's world ranking.
Croatia are ranked 12th in the world by Gracenote's world ranking methodology
and Japan are 18th. Both have risen sharply in 2022 with Croatia up 10
places from 22nd and Japan improving from 29th.
Most of those improvements were
before the World Cup as they entered the competition in 14th and 21st
respectively.
Gracenote's predictions give 2018 World Cup finalists Croatia 58%
chance of reaching their third quarter-final in six appearances. Japan have 42%
chance of reaching the last eight for the first time in seven attempts, having
fallen at this stage three times before (2002, 2010, 2018).

This will be the third World Cup meeting between the sides.
Croatia won 1-0 in 1998 and they drew 0-0 in 2006, both in the group stage.
Their only other meeting saw Japan win a 4-3 thriller in the 1997 Kirin Cup Soccer - basically a friendly tournament.

Four years ago Croatia became the first real surprise team in a World Cup final since Czechoslovakia in 1962.
In between hosts England beating West Germany in 1966 and France beating Croatia in 2018, every World Cup final was between two of France, Germany, Argentina, Spain, the Netherlands, Italy and Brazil.
Could Croatia have a similar run again - or can Japan match the performances that saw them beat Germany and Spain - and go all the way?

Japan averaged only 32% possession across their three group games. Their two wins over Spain and Germany came with 18% and 26% possession respectively.

Japan are in the last 16 for the fourth time - but they have never been beyond this round.
In 2002 they were beaten by Turkey. In 2010 it was Paraguay - and four years ago Belgium beat them.
They are bidding to become the third Asian side to reach the quarter-finals - after North Korea in 1966 and South Korea in 2002.

Croatia got the point they needed in their final group game against Belgium to qualify for the knockout stages.
They also drew 0-0 with Morocco, as well as battering Canada 4-1.

Japan had a remarkable group stage to qualify for this game.
First they beat Germany, ranked 11th in the world, 2-1. Then they lost 1-0 to Costa Rica, who are 31st in the world. And then beat the eighth top team Spain 2-1.
If they can beat Germany and Spain, they should fancy their chances against anyone really.
