Portugal and Uruguay played out the fifth draw in seven matches at this FIFA U-20 World Cup. Wasteful finishing existing throughout a goalless encounter, which left all four teams on one point in Group B, following Cameroon's 1-1 tie with New Zealand earlier today.
With Uruguay missing the influential Adrian Luna, the first half was largely void of goal-mouth action, with a number of fouls and misplaced passes.
Nelson Oliveira did animate the Portuguese supporters on 31 minutes, teasing his way past two opponents before firing just over the bar.
The second half was a different story. It took just seven minutes for Celeste captain Diego Polenta to unleash a stunning thunderbolt, which crashed back off the post.
The woodwork then denied a delightful free-kick from Oliveria, who should have done better than direct a free header straight at goalkeeper Ichazo moments later.
Portugal No1 Mika then pulled off a superb reflex save to keep out a Ramon Arias header.
Sergio Oliveira received a second yellow card with 11 minutes remaining, but despite being at a numerical disadvantage, the Europeans continued to probe for a goal. They didn't get it, however, leaving the pool wide open.
