Charlie Austin led the way as Southampton made a comfortable start to their Europa League campaign with a facile victory over Sparta Prague.
The English team were awarded a penalty on five minutes when visiting defender Costa Nhamoinesu was harshly adjudged to have handled in the box.
Austin came out on top of a spat with team-mate Dusan Tadic over who would adopt spot kick duties and the former QPR striker promptly dispatched his effort with minimum fuss.
The Saints No 10 then headed home a Cuco Martina delivery only for the 'goal' to be ruled out for offside.
