Argentina completed the turnaround from the shock opening World Cup loss to Saudi Arabia by qualifying for the last 16 in impressive style against Poland - who went through on goal difference having finished level on points with Mexico.

Lionel Messi was the catalyst for the crucial win against Mexico that got Argentina's campaign back on track, and he was instrumental again as they illustrated why they were regarded as one of the tournament favourites to set up a second-round match against Australia.

Poland were set to progress by virtue of the Fifa Fair Play rule for having fewer yellow cards than Mexico - until Saudi Arabia pulled one back deep into stoppage time in their 2-1 loss to the Concacaf side.

That meant goal difference was decisive for the Poles, who will next face France.

Argentina ran out comfortable winners with second-half goals from Brighton's Alexis Mac Allister and Manchester City striker Julian Alvarez, but the game still held real drama and jeopardy in the closing stages as Poland knew another goal conceded, or another goal for Mexico against the Saudis, would send them out on goals scored.
