After Ismaili downed Hilal 1-0 in the round of 16 first leg, the Brazilian coach was convinced that the Dervishes lucked out.

The coastal side won the return leg 3-1 to ease to the Champions League group stage but Campos partly put his men's second loss down to 'refereeing mistakes'.

"We were far better than Ismaili. The result doesn't really reflect both teams' outcome, it was an undeserved defeat," he said after the match.

"We would have won the game if it wasn't for the refereeing mistakes and our defenders' lack of concentration. That's why I'm angry."

Hilal took the lead in Sunday's match but hosts Ismaili fiercely replied with three goals to seal a 4-1 aggregate win.

Ismaili reached the Champions League group stage for the first time in seven years.
