BAYER LEVERKUSEN 1 SCHALKE 0

Schalke went into the game with the advantage of an extra two days' rest from European duty in midweek but it was Leverkusen who showed more stamina as they clinched victory with a dream goal from Manuel Friedrich five minutes from time.

Friedrich took the ball in from the touchline on the right and swept in a superb shot from around 35 metres that beat Schalke keeper Manuel Neuer and effectively took Leverkusen into third place.

EINTRACHT FRANKFURT 1 WERDER BREMEN 0

Werder, feeling the effects of a UEFA Cup game on Thursday, started badly and were down to 10 men in the 40th minute when Diego barged into Ioannis Amanatidis off the ball.

Amanatidis put Eintracht ahead with a swift break in the 56th minute and the home side held on as Werder suddenly upped their game, playing much better with 10 than they had with 11.

STUTTGART 3 KARLSRUHE 1

Stuttgart scored three goals for the second weekend in succession as they clinched a satisfying derby win.

Mario Gomez struck his 11th league goal of the season to put the home side ahead in the fifth minute, side-footing in from outside the area after a rebound had dropped to him kindly.

Roberto Hilbert made it 2-0 in the 25th minute, stabbing in from close range, but Stuttgart eased up and might easily have paid the price, with Tamas Hajnal getting a goal back when he squeezed in a shot nine minutes from time.

Stuttgart were looking nervous before Cacau, set up by Antonio da Silva's fine pass, settled the match two minutes from the end.
