Tonight at the Fisht Stadium Sochi, two of the best contenders will battle it out. To win tonight's match, Portugal will need to dominate the midfield, so it is likely that Bernardo Silva will return to the starting XI, as will Gonçalo Guedes, who brings greater aggression and real defensive instincts to the engine room.
The teams will go to the field knowing who they will fight next it they win. With Luis Suarez and Edinson Cavani teaming up on one side and Cristiano Ronaldo on the other, even the tiniest lapse in concentration could prove fatal. It is their third time facing each other and the first time at the FIFA World Cup.
Oscar Tabarez and Fernando Santos are two of the most experienced coaches at the World Cup. They will be doing everything in their power to ensure that their players are in the best possible frame of mind.
