Spain vs Portugal
Venue: Fisht Stadium
Kick off: 7PM
Portugal had endured a roller coaster ride in the recent months.
The Fernando Santos-led side defeated Switzerland, Egypt and Algeria, while they lost 0-3 to Netherlands and settled for draw against Tunisia and Belgium in their last six matches.
The Euro 2016 champions, who failed to make beyond group stage at Brazil 2014, will hope to see their players finding form quickly against a dangerous Spain.
Though Spain have been in impressive form in the lead-up to the showpiece event, they were hit by the shocking axing of their head coach Julen Lopetegui.
Lopetegui, whose sacking came after he was named Real Madrid coach, was replaced by former Bolton Wanderers centre-back Fernando Hierro as the manager of Spain for the 2018 FIFA World Cup.
Spain, who are among the favourites for the World Cup title, have remained unbeaten in the 20 games they had played under Lopetegui.
In the last 36 games against each other, Spain have won 18 games against Portugal.
