World Cup 2018: 3 twists that could happen in the final round of group stages

#2 Iran to knock Portugal out

Ronaldo's efforts to go in vain?

Group B has been a talking point of the World Cup so far. The thrilling 3-3 draw between Spain and Portugal, Cristiano Ronaldo's hat-trick, Iran's defending against Spain, Morocco's heart-winning performance and more.

After two matches, Spain and Portugal sit first and second on the points table with four points each. Asian side Iran is just behind with three points, while Morocco has been eliminated.

In the final group fixture, Portugal will be taking on Iran and the Cristiano Ronaldo-led team are expected to see it through to ensure a spot in the next round.

However, Euro 2016 winners could receive a setback from their opponents. A solid defence to keep Ronaldo and co silent and a scrambled goal would be enough for Iran to take Portugal's round of 16. And that will be a twist that no one saw coming.
