Diao - scoring his first league goal in approaching eight years - rifled in a last-gasp winner to break Pompey's hearts after Robert Huth had earlier headed in an equaliser for the 10-man visitors following Frederic Piquionne's first-half opener for the troubled hosts. Pompey enjoyed more possession in the first period and Nadir Belhadj nearly gave them the lead when his 20-yard scorcher just whistled over the bar after 25 minutes. Quincy Owusu-Abeyie's power and pace caused Stoke plenty of problems on the left side and he played a huge part in helping Pompey break the deadlock after 35 minutes when he played a slick one-two with Jamie O'Hara on the edge of the Stoke box, before unleashing a powerful, low effort which Thomas Sorensen could only push across goal, with Piquionne first on the scene to net the rebound. The Lyon loanee's effort turned up the volume at Fratton Park, but Tuncay nearly levelled for the visitors five minutes before the break when he twisted, turned and made space on the left-hand side of the Pompey box, but goalkeeper David James beat his effort away. Stoke came out in more determined fashion after the break and levelled after 50 minutes when a right-wing corner picked out Huth and the giant German rose highest to head in his third league goal of the season. But Stoke's cause was not helped when Andy Wilkinson was sent for an early bath after he picked up his second bookable offence in the 73rd minute. Both sides went in search of a winner, and it arrived for Stoke in stoppage time when Ricardo Fuller's mazy run picked out Diao and he blasted in to help the Potters to only their second away win this season and consolidate 11th place. Pompey remain bottom and are eight points from safety.
