The Democratic Republic of Congo has lost their second group-stage match 1-0 to Colombia, putting their qualification for the World Cup knockout stage hanging in the balance.

Colombian coach Nestor Lorenzo praised his side's composure and attacking variety in the Group K match on Tuesday in Guadalajara. With the victory, they have now qualified for the round of 32 with a match to spare.

Colombia, who opened with a 3-1 win over Uzbekistan, moved to six points from two games after breaking down a disciplined DRC side, with Lorenzo saying his team had grown in performance despite the pressure of a tight contest.

Lorenzo said Colombia had to use different channels and lanes to find space against DRC compact defence.

Colombia face Portugal next, with Lorenzo calling them "a huge team" and a major contender to win the World Cup.

Colombia must not focus only on Cristiano Ronaldo. "You have to be very careful and not leave him alone in different situations, especially whenever he is close to the goal area. But Portugal is a complete team. You should not only point out Cristiano."

Lorenzo thanked the large Colombian support in Mexico, saying the players were inspired by the "yellow shirt" filling the stadium.

DRC had drawn 1-1 with Portugal in their first game and will now face Uzbekistan, who lost their first match 3-1 to Colombia.
