David Humphreys gave a masterful performance to maintain Ulster's proud home record and their interest in the Heineken Cup.

The Irish playmaker shrugged off the effects of a bruised toe to score a late try and drop goal to give Ulster their 11th successive win in Europe at Ravenhill.

Scrum-half Kieran Campbell also grabbed a stunning solo effort to set up their third victory in four years over Stade Francais. The French champions missed a late penalty to grab at least grab a bonus point as Pool Six was thrown wide open once again.

Ulster were twice forced to come from behind as the pool leaders stunned Ravenhill with a try inside three minutes.

Augustin Pichot danced his way inside and out of the Ulster defence who could not lay a hand on the little Puma. David Skrela delivered a piercing kick for full-back Juan Hernandez to slide over for the try. Skrela converted for a seven-point lead.

Mirco Bergamasco came close to extending the lead but the Italian showed poor footballing skills as he poked the ball over the dead-ball line.

Relief turned to jubilation inside Ravenhill when a moment of magic from Campbell.

The speedy scrum-half launched into a one-man counter attack from a quick tap penalty, waited for support to catch up but stepped on the gas when none arrived for a superb try. Ulster joy was tempered when Humphreys missed the simple conversion.

Stade wasted further chances, Skrela hit the post twice and they were made to pay in the final ten minutes when Humphreys took control behind Ulster's rejuvenated pack.

The forwards stole possession, Bell made the telling break but Humphreys added the touch of class stepping inside and then out of the last defender. Humphreys added the conversion and then a monster drop goal to deny Stade even a bonus point.
