Arsenal boss Arsene Wenger accused Blackburn of waging "violence" against his side as they conceded a late equaliser at Ewood Park.
Wenger refused to blame Lehmann for his costly error
Gunners keeper Jens Lehmann let David Dunn's strike slip through his hands in the tempestuous draw,
But Wenger was more concerned with Rovers' approach and said: "I felt there was a desire for violence more than commitment in their challenges.
"We dealt well with the problem we had against a team that was over-physical."
Wenger added: "My team showed the correct attitude and we are frustrated because we should be going home with the three points."
Meanwhile, Wenger admitted that Lehmann was "extremely down" after his costly error.
It was the second time this season the German has been punished for a lapse in concentration.
On the opening day he gifted a goal to Fulham's David Healy but Arsenal recovered and went on to secure a victory.
Wenger stated: "Jens is really unhappy and really down in the dressing room.
"I do not need to tell him, though, he has made a mistake. We do not want to blame him. We want to keep the positives.
"Of course he will be concerned about what has happened but we have to prepare for the next game now."
Wenger's accusation was dismissed by his managerial counterpart Mark Hughes.
"That attitude by Wenger surprises me," said Hughes said.
"The worst challenge was by Van Persie on Stephen Warnock.
"It was very competitive and I thought we dominated the game. We were the better side. We showed great character and equipped ourselves well against a top side."
"It sets down a marker as far as I am concerned."
