Newly-promoted Young Boys of Bern are the new leaders of the Swiss football league following a 2-1 home win over Aarau on Saturday.

The side from the Swiss capital took advantage of an unexpected slip-up by former leaders FC Zurich, who suffered a 3-0 defeat to a Lucerne side previously without a win this season.

FC Zurich were not helped by the dismissal of their influential midfielder Kawelaschwili who was shown the red card for the second time this month.

Servette Geneva missed the chance to join Young Boys at the top of the table after losing 2-1 at home to Marcel Koller's rapidly improving St Gallen.

Defending champions Grasshoppers Zurich moved up to second place with a 1-0 win over Basel, although Hans-Peter Zaugg's men were lucky to see an apparently legitimate goal from Basel's Jean-Michel Tchouga disallowed in the dying seconds of the match.

Sion also enjoyed a slice of overdue good fortune after beating Lausanne 1-0 with a penalty awarded in the 93rd minute. Saturday's win continues the fightback by the canton Valais side who have already been deducted three points for fielding too many foreign players in one match this season and are facing a further seven point deduction over an earlier financial irregularity.
