Group B has been the source of some great stories at the 2018 World Cup, including arguably the most entertaining game on matchday one between Spain and Portugal, which ended 3-3. Heading into the final fixtures, it is still close and three of the teams can still reach the last-16 stage by finishing in the top two, with just Morocco – unlucky to be pointless – having already been eliminated.

Iran’s win against the Africans on gameday one was their first at a World Cup since 1998 and just a second in their history, but they will require another three points when they face Portugal on Monday afternoon in Saransk if they are to leapfrog their Iberian opponents.

Carlos Queiroz is renowned as a master tactician and it will be interesting to see how he attempts to tackle the country of his birth, as well as stopping talisman Cristiano Ronaldo – the two, of course, worked brilliantly together during their spell at Manchester United, winning the Champions League in 2008. Though they are a point behind both Spain and Portugal, a draw is unlikely to be enough – Iran would then be relying on Morocco to win in the other game, and by at least two goals.

Portugal are in a strong position, though they have been relying heavily on Ronaldo to this point. The Real Madrid forward has four goals from two games and now trails England’s Harry Kane in the Golden Boot race after his hat-trick against Panama. Breaking down Team Melli is unlikely to be straightforward, as they have scored and conceded just one apiece in this tournament.

With 139 markets to choose from, is the place to bet for the 2018 World Cup and they are heavily backing three points for Portugal at 1.65. Iran are 5.75 to record what would be a historic victory, while there are plenty of other things to stake on, including whether or not both sides will find the net (yes/no at 2.30/1.55).

There are also extensive betting options for Spain vs Morocco, which also kicks-off at 20:00 (CEST) on Monday night. Season bets allow predictions on which side will lift the trophy on 15th July in Moscow.
