من الأفضل إلى الأسوأ - ترتيب جميع فرق كأس العالم بعد مباراة واحدة

Argentina kicked off their World Cup defence with an emphatic win - but are not the best side at this World Cup so far, according to our BBC Sport experts.

We've brought together a small team of journalists who, between them, have watched every side's opening game.

And they have ranked all 48 teams at the tournament, from first to last.

You'll also have a chance to rank every nation yourself at the bottom of this page.

Lived up to pre-tournament hype with rampant second-half performance. Strength in every position. Deserved favourites.

Scored four. Could have had more.
