i think that handball (first thought to be by haji) was by a hoffenheim attacker. they played it back several times. in fact that's what the schalke player's were complaining to the referee about. the ball got to the schalke players hand after first hitting a hoffenheim player's hand. (var apparently ok'd the first but called the second). that first infraction should have had the ball going the other way according to shalke. they were claiming there should have been no penalty.
