Cristiano Ronaldo's Portugal begin their Group K campaign against DR Congo, aiming to avoid any early slip-ups after the tournament's surprising opening results.
Portugal enter as favourites thanks to a star-studded squad featuring Ronaldo, Bruno Fernandes, Bernardo Silva and Rúben Dias, while DR Congo will rely on the experience of Yoane Wissa, Cédric Bakambu and Chancel Mbemba.
With Spain managing to clinch just one point against Cape Verde and Australia upsetting Turkey, this World Cup has already shown that no result can be taken for granted, making Portugal's opener a potentially tricky affair.
