Leyton Orient chairman Barry Hearn has told ESPNsoccernet he believes Arsenal underestimated his side in their FA Cup clash, but admitted he is not expecting Arsene Wenger to make the same mistake in their replay at Emirates Stadium.
Orient snatched a dramatic 1-1 draw at Brisbane Road on Sunday and will now travel to North London to battle the Gunners for the right to face Manchester United in the FA Cup quarter-finals.
Wenger made several changes from the team that beat Barcelona last Wednesday, with Jack Wilshere, Cesc Fabgreas, Samir Nasri, Gael Clichy, Laurent Koscielny and Robin van Persie all rested, but Hearn is expecting to see Arsenal's star players return for their replay in a fortnight.
"I just hope that we don't get beaten 27-0 in the replay," Hearn told ESPNsoccernet. "Believe me it will be a much stronger Arsenal team next time round.
"I think Arsene Wenger, a manager I admire, was a touch complacent and didn't put out all his big guns. Now he is lumbered with an extra fixture he doesn't want, and we have a fixture we definitely do want.
"The fixture congestion it has created for arsenal is a nightmare, but for us its dream come true."
Orient's FA Cup run has seen the club receive a massive financial boost and Hearn says earning a replay has now ensured that the League One club will make a profit.
But he stressed an equally important benefit of the run has been the platform given to the East Londoners to publicly state their oppsosition to West Ham's Olympic Stadium plans, which Hearn feels could cripple Orient.
"The FA Cup run has guaranteed that Leyton Orient has broken even, but now the replay has ensured that we will become a rarity in football, and run into profits," Hearn said. "But I am sure our manager will want to find ways of spending it, so it won't last too long.
"We have also got ourselves a platform by drawing with Arsenal, a platform to ensure we get a hearing in the Olympic debate."
