Serious star power will be on display when Spain meet Portugal in the World Cup on Friday.

Cristiano Ronaldo and Co will open their campaign in Russia as they attempt to become just the fourth nation to win the European Championship and World Cup consecutively.

Spain, however, will be a force to be reckoned with, even after firing Julen Lopetegui and replacing him with Fernando Hierro on the eve of the tournament.

Check out a preview of the heavyweight encounter in the video below.
