Luiz Adriano, who scored five goals in Shakhtar Donetsk`s record-tying 7-0 Champions League win at BATE Borisov on Tuesday, said he was the victim of racist chanting from a section of the crowd.
"I heard rude abuse...racist ones," the Brazilian marksman was quoted as saying on Shakhtar`s website (http://shakhtar.com/en/).
"Supporters behaved improperly and that is why I am disappointed and feel resentment. It was an ugly act from their side."
On a record-breaking night, Luiz Adriano became the first player in the history of the competition to score four goals in the first half.
He also joined Barcelona`s Lionel Messi as the only players to hit five goals in a Champions League game.
Shakhtar`s 6-0 halftime lead created a new mark for the competition and the margin of victory equalled the best away from home set by Olympique Marseille when they triumphed 7-0 at MSK Zilina in 2010.
Ukrainians Shakhtar are now second in Group H on five points, two behind leaders Porto who beat Athletic Bilbao 2-1.
BATE are third with three points from three matches while Bilbao have one.
Luiz Adriano scored in the 28th, 37th, 40th, 44th and 82nd minutes -- two of his strikes coming from penalties.
"I am excited that my record helped the team. It was a beautiful and historic victory," he said.
