Diego Forlan hails group winners
Uruguay striker Diego Forlan hailed the performance of his team-mates as they topped Group A with a 1-0 win over fellow qualifiers Mexico.
Uruguay and Mexico advanced from the group.
Despite Uruguay's win, Mexico advanced because their goal difference was superior to South Africa's, who also finished with four points. Uruguay now look likely to face Diego Maradona's Argentina in the second round.
"The important thing is that we qualified in first place," Forlan said. "They controlled the ball well and in truth it was quite hard for us."
Fellow striker Luis Suarez, whose header sealed the win added: "We knew we had two results that benefited us. But before the match our goal was to get the three points and be group leaders. Luckily we reached out first goal, which was to advance from the first round."
Uruguay manager Oscar Tabarez said he was just pleased to have taken them beyond the group stage.
''Of course we've analysed all the possibilities for us,'' he said. ''I think so far in this phase we've showed that we are a tough team to tackle for the others. We are trying to do what we had exactly in mind before the tournament. Now I don't think we've achieved that yet, but Uruguay is now a difficult opponent for anybody.
''This is what we have seen so far and if you look at the history of Uruguay in the last few World Cups, this win is really satisfying and the news from Montevideo is very good.''
Mexico boss Javier Aguirre felt his side lacked energy, but vowed to bounce back stronger in the next round.
He said: ''I guess the attitude (was missing). We really did not want to win the match. I guess what we were missing was the energy.
''We conceded the goal and then we tried to recover, but we couldn't and then towards the end we lost our spirit. We're now in the round of 16. We'll try to recover and do our best to go far in this competition.''
