Moscow - Brazilian striker Ari struck twice and Ibson also scored on Tuesday to lead Spartak Moscow to a 3-0 win over Zilina in the Champions League.
The 24-year-old Ari hit a goal in each half in a match the hosts dominated to give Spartak two wins out of two in Group F.
Ari's first came in the 34th minute, looping a header over goalkeeper Martin Dubravka from eight meters. The ball was cleared, but correctly adjudged to have crossed the goal line.
He tapped the ball into an empty net from Dmitri Kombarov's low cross in the 64th minutes to double the lead. Ari's compatriot, Ibson, struck in the last minute.
Spartak outclassed its Slovakian opponents with Brazilian midfielder Alex and winger Aiden McGeady orchestrating most attacks.
