Nobody would have hand-picked the tournament's two worst teams to launch the 2018 World Cup, but when Russia and Saudi Arabia meet on Thursday form will be irrelevant as the world's biggest sporting festival explodes into life in Moscow.
Hosts Russia, and Saudi Arabia are the two lowest-ranked teams at the tournament by some distance and they are both in dire form. But their clash will set the tone for the global showpiece.
Partly due to a lack of competitive matches, Russia have slipped to 70th in the FIFA rankings, which sounds shockingly low for a World Cup team until you glance up to see the Saudis, despite securing automatic qualification from a competitive Asian confederation, at 67.
Despite failing to win in seven matches stretching back to October, 2017, the hosts still have realistic hopes of making it to the second round for the first time in more than 30 years after being drawn in a group also containing Egypt and Uruguay.
Russia coach Stanislav Cherchesov has been working overtime trying to rebuild his team, particularly defensively, after a cruel run of serious injuries to some of his most experienced operators, but the tournament has arrived without him showing much evidence of progress.
His team last tasted success via a 4-2 victory over South Korea - and even that win needed two own goals - and their most recent warm-ups brought defeat by Austria and a 1-1 draw with Turkey.
In those games, Russia's laboured build-up play and careless passing looked light-years away from the irresistible, quicksilver side that lit up the European championship a decade ago.
That 2008 tournament, in which they reached the semifinals, is something of an island of success for a nation who failed to qualify for the World Cups either side of it and made no impression in 2014 when they finished behind Belgium and Algeria.
That historical and recent lack of form means that few in Russia are holding out much hope of glory on home soil but the players will almost certainly be lifted by the occasion and by finally getting their teeth into a competitive match.
They also have a puncher's chance in the shape of striker Fyodor Smolov, who has become a scoring machine since being left out of the squad in 2014 with more than 60 goals over the last three seasons for his club Krasnodar.
If they are going to do it against anyone then it should be against a Saudi team coming off the back of successive friendly losses to Italy, Peru and Germany, though they showed patches of encouraging form and did beat Algeria and Greece in May.
Fedor Smolov will line up as a lone striker for Russia as the World Cup hosts attempt to end a seven-match winless run in the opening game of the tournament against Saudi Arabia in Moscow on Thursday.
The Krasnodar forward will be supported by Aleksandr Golovin and Alexander Samedov out wide as Russia bid to win a World Cup game for the first time since 2002.
Saudi Arabia return to the tournament after a 12-year absence and are the second-lowest ranked side in the competition at 67th in the world, three places above Russia.
Saudi coach Juan Antonio Pizzi will hope Mohammed Al-Sahlawi, who bagged a staggering 16 goals in qualifying, can snap a nine-game scoring drought in Russia.
