The World Cup's final round of group games is under way, and drama is expected when Groups C and D are wrapped up on Wednesday – with all eight sides involved having plenty to play for.
Two-time winners Argentina were facing a humiliating exit after their stunning collapse against Saudi Arabia, but a dose of Lionel Messi magic against Mexico has teed them up for a winner-take-all clash with Group C leaders Poland.
While Saudi Arabia know a victory against Mexico would guarantee them safe passage to the last 16, El Tri must win to have any chance of avoiding their first group-stage exit since 1978.
In Group D, meanwhile, France may be pretty much there in terms of a last-16 place, but Didier Deschamps' men still require a point against Tunisia to be mathematically certain of top spot.
Tunisia must upset the holders to have a chance of progressing, while Euro 2020 semi-finalists Denmark will be eliminated if they fail to beat Australia.
