Although he was delighted with qualification for the Round of 16, Paraguay boss Gerardo Martino called for improvement from his players after their 0-0 draw with New Zealand.

The South Americans were wasteful in attack whish surprised their manager who admitted he was unhappy with how his team performed.

"We played very badly in the first half and we played better in the second half," he said.

"I'm pleased with the qualification but not with the way we played.

"We had a lot of problems in an area where we didn't expect, and that was in attack."
