HAMILTON, New Zealand: Portugal coach Helio Sousa said on Wednesday ball possession for long periods of time helped his side beat Qatar in their Group C clash at FFA U-20 World Cup. Striker Ivo scored twice (42 and 66) while Andrea Silva (34) and substitute Joao Vigario (74) managed one goal each as an impressive Portugal cruised to a 4-0 win to seal a berth in the round of 16. "We played a good game today. We tried to control the ball, to create opportunities to score," Sousa said after his side posted their second consecutive win in the tournament. "The pitch was a bit difficult. It was hard to play. It was tough to keep the ball in play but we showed good touch to create opportunities," Sousa said. "Qatar was waiting. Their lines were a bit old. We had to have patience to score," Sousa said. "After the first goal, we scored second and then the third to be in the game. We got those goals and it was a good game for us," he added. Sousa said winning two games out of two has made things easy for his side ahead of their third Group C clash. "That's what we are playing for - to go to the last game with a chance to keep things in our favour," Sousa said. "Now we have two (favourable) results before playing that match. That's great for us. We have seven goals, no goals conceded. We want to stay in first place," he added. When asked about Qatar's performance on Wednesday, a thoughtful Sousa said: "Qatar, I think, did more or less the same things they did against Colombia. But I think maybe we were more capable and we kept more of the ball possession in the danger zones." He explained: "They could have counter-attacked and made things dangerous for us. They were capable of creating trouble for us but we were capable of resolving those situations." Sousa said: "But that's the game. It is difficult for any team to control the game for 90 minutes. We know that we had some troublesome moments but we were united to keep those problems away. Sometimes it was difficult but we managed to survive those (tough) moments." Portugal take on Colombia on June 6 in Dunedin.
