ATHENS, October 15 (World Cup Qualifying) - Switzerland ended Greece's 100% record in World Cup Qualifying after claiming a deserved victory over Otto Rehhagel's men in a closely-contested Group Two encounter at the Georgios Karaiskakis Stadium in Athens.
Alexander Frei's first-half penalty gave Ottmar Hitzfeld's men the lead before Angelos Charisteas levelled for an out-of-sorts Greek side after 68 minutes.
But Blaise Nkufo latched on to substitute Hakan Yakin's superb threaded pass before rounding home goalkeeper Kostas Chalkias and slotting home 13 minutes from full-time to snatch three precious points for the Swiss.
The Greeks remain top of the section with nine points but the race for qualification is now wide open with second-placed Israel just a point behind while the Swiss are third with seven.
Having strolled to a 3-0 success against Moldova four days earlier, Greece found the going tough against the Swiss, with Tranquillo Barnetta's deflected shot flashing wide of the left post after just six minutes.
Some slick passing from the visitors then created an opening for Frei but the Borussia Dortmund striker's rasping left-footed drive was saved by Chalkias.
It was 21 minutes before Greece had their first sight of goal but Angelos Basinas's 30-yard free-kick was comfortably saved by Diego Benaglio.
Georgios Samaras then wasted Greece's best chance of the half when he blazed over after a clever dummy. The visitors were always a threat, however, and they broke the deadlock just four minutes before half-time when West Ham midfielder Valon Behrami was felled by Avraam Papadopoulos as he tried to latch on to a through ball.
Spanish referee Luis Medina Cantalejo had no hesitation in awarding a penalty and Frei slotted the ball past Chalkias into the bottom left corner.
Rehhagel sent on Nikolaos Lymperopoulos for the ineffective Theofanis Gekas at half-time, but Switzerland forged the first chance of the half through Gokhan Inler, who skipped past two defenders before firing wide.
Fit-again talisman Georgios Karagounis replaced Samaras just after the hour mark though and his introduction heralded the equaliser after 68 minutes, the Panathinaikos man's left-wing cross converted by Charisteas from close range.
Just as it seemed Greece would salvage a point, however, Hitzfeld introduced a super-sub of his own in Yakin, who replaced Frei.
Yakin's first act was to pick out Nkufo, who rounded Chalkias before sidefooting the ball into the empty net to send the travelling Swiss supporters into raptures.
