(Reuters) - Rustic defending in the land of the beautiful game may seem like an insult for Brazilian fans, but it served 10-man Greece well when the team earned a point in a goalless World Cup Group C draw with Japan in Natal on Thursday.

The Greeks, who had captain Kostas Katsouranis sent off for a second booking late in the first half, quickly reverted to their tried and tested method of defending at all costs, a strategy that brought them a surprise triumph at Euro 2004.

With both teams desperate to win to stay in contention for a top-two finish in the group, the Greeks will undoubtedly be the happier side after they had to drop deep and soak up almost an hour of relentless Japanese attacks.

Japan, which lost its Group C opener to Ivory Coast, laid siege, but even when coach Alberto Zaccheroni brought on attacking midfielder Shinji Kagawa, the team couldn't score.

Initially, it was a free-flowing game, with both teams out to score, but Katsouranis' red card and an injury to striker Kostas Mitroglou forced Greece coach Fernando Santos to change plans.

Off came skillful attacking forward Yannis Fetfatzidis, and on came 37-year-old veteran Giorgos Karagounis, one of two Euro 2004 survivors (along with Katsouranis) on the squad, to control possession and add experience during a desperate second half.

Karagounis provided control against the charging Japanese, with winger Giorgos Samaras the Greeks' target whenever they tried to go forward or shave a few seconds off the clock.

Japan has only itself to blame for not converting at least one chance, with its finishing leaving a lot to be desired. The team completed almost four times as many passes as the Greeks, but always failed at the final hurdle.

Yoshito Okubo, Keisuke Honda and Atsuto Ushida repeatedly came close but either fired wide or were denied by keeper Orestis Karnezis.

Greece central defenders Sokratis Papastathopoulos and Kostas Manolas had nearly flawless games, with the Japanese opting to try and cut in from the wings or break the deadlock from set pieces late in the game.

To add insult to injury, Greece coach Fernando Santos went all out toward the end, bringing on winger Dimitris Salpingidis in place of Panagiotis Kone, but it would have been an injustice had Greece scored.

The result may be a relief for the Greeks, but both teams must now win their final games to have any chance of qualifying.

There were at least some happy fans, with Colombia sealing its round of 16 spot as a result of the draw after it beat Ivory Coast 2-1 earlier Thursday.
