Blackburn manager Sam Allardyce took great delight in getting the better of Arsenal counterpart Arsene Wenger in his side's 2-1 win at Ewood Park.
Allardyce targeted goalkeeper Lucasz Fabianksi from set-pieces by crowding players into the six-yard area.
It paid off as both Blackburn's goals came from corners when Fabianski failed to deal with Morten Gamst Pedersen's delivery; David Dunn cancelling out Robin van Persie's opener from close range before Chris Samba headed in from barely three yards.
"We set out to spoil them and the spoiling tactics worked," said Allardyce.
"They (Arsenal) are one of the big four and when you are beating one of them it is not expected.
"Then it is a bit of emotion after the game that they are upset about something which has not gone their way. But I can assure you that most of the time, throughout the season, the 'big boys' get the rub of the green more than the likes of Blackburn Rovers.
"That is not done on purpose by the officials it is just a psychological problem they have because they are human beings and the pressure they get put under turns them that way slightly.
"We all know that and we have to live with that."
Wenger called the tactic "unfair" but the Rovers boss felt he was fully justified, considering the Poland international's history of being susceptible under pressure.
"He is entitled to his opinion. Whatever has happened between us in the past, and it has been a little frosty on occasions, I have always respected him as a manager," added Allardyce of Wenger.
"He is a terrific manager and what he has done for Arsenal is magnificent but we can't play like them so we didn't."
