Day two of the World Cup brings its first big fixture with 2016 European Championship winners Portugal facing their Iberian rivals Spain in Sochi.

La Roja saw their preparation thrown into disarray when it was announced coach Julen Lopetegui would succeed Zinedine Zidane as Real Madrid boss, a move which saw the Spanish football association sack the 51-year-old for failing to disclose the fact he had opened negotiations with the Champions League winners.

Former Los Blancos player Fernando Hierro has stepped into the breach and as starts go, facing Cristiano Ronaldo and co. in Spain's Group B opener is far from ideal.

If Portugal are to advance as Group B winners then overcoming the 2010 World Cup winners will be the perfect start.
