Persepolis boss Mustafa Denizli insists his side won't repeat the mistakes of their last matchday and will seal qualification to the AFC Champions League Round of 16 when they host Saudi giants Al Hilal on Tuesday.
The Tehran outfit were denied a spot in the next phase on matchday four when they conceded a stoppage-time Lawrence Quaye equaliser to draw 1-1 with Qatari side Al Gharafa.
Persepolis are top of the group with eight points from four games, ahead of Al Hilal (six points), Al Gharafa (three) and Al Shabab (two).
However, Denizli told reporters ahead of Tuesday's game he was confident they'd seal their progress against Al Hilal.
“It was an unlucky incident that we conceded in the last few minutes of the game and we didn’t get the the win,” said Denizli.
“But tomorrow we won’t repeat any similar mistakes, since we’ll be playing the strongest team in the group.”
He added: “In the AFC Champions League, we have got good results and of course, this process will be continued in our two remaining matches.
“We’ll make a good day for Iranian football tomorrow when the game will attract many supporters to the stadium."
Al Hilal coach Ivan Hasek admitted a huge Azadi Stadium crowd would be difficult for his players, but insisted they weren't afraid of the prospect.
“We know they are always backed by a large number of fans and they are really enthusiastic, but we’re not afraid of that. The fans add spice to our game,” he said.
“We are well prepared and look forward to the match. They are a very smart team.
"In the first leg match they had one counter attack and that was enough for them to score their equaliser. We’ll treat this game very importantly and we know how sensitive it is."
