Germany goalkeeper Manuel Neuer conceded a late own goal tonight as Hoffenheim kept up their dream start to the season, claiming their third-straight victory with a 2-0 win over Schalke.
With time almost up, Hoffenheim midfielder Sejad Salihovic clattered the Schalke goalpost with a free-kick and Neuer could only watch as the ball bounced off his chest into the net, deep into extra time.
Earlier, 22-year-old Ghana defender Isaac Vorsah's first-half header had given the hosts the lead. It was his second strike in two games as his late goal against St Pauli settled his side's last match a fortnight ago.
Schalke, who gave a debut to Dutch striker Klaas-Jan Huntelaar, have now lost all three games.
The result is further bad news for Schalke who will go into next week's UEFA Champions League match against Lyon with three defeats as last season's runners-up endure a nightmare start to the season.
Hoffenheim took the lead when captain Andreas Beck curled in a cross and with Vorsah unmarked in the area, the Black Star defender launched his header past Neuer.
The Germany goalkeeper had earlier kept his side in the game with several close-range saves, while Huntelaar squandered a golden chance to put his side ahead after only 10 minutes when he fired wide.
Kaiserslautern, Mainz, Hamburg and Hanover can all join Hoffenheim at the top of the table tomorrow as joint leaders if they win their respective matches.
