Following Lehmann's latest attack in the aftermath of Tuesday night's Champions League elimination at Liverpool, Almunia told the Guardian: "Every morning I wake up.
"I know it is going to be the same. I've had to put up with it every day since he was out of the team and even before then. I wake up and I know what it is going to be like. But I don't care about him any more. He can say what he likes. I come into training and I work with Lukasz Fabianski and Vito Mannone. They are better goalkeepers than him anyway.
"It's his problem, not mine, and I don't see why I should try to talk to him about it. The truth is I don't want to talk to him. I came into training this morning and one of the press officers told me he had been saying bad things about me in the newspapers again. It didn't surprise me. The truth is I have got used to reading these things from him. If he was someone important to me, I would try to talk to him and see what the problem is. But he's not. So we don't talk.
"I've never been in a situation like this before in my career," he says. "Normally we goalkeepers have so much respect for each other. Why he doesn't respect me, I don't know. But I don't want any relationship with him. I try not to let what he says enter my mind because it's not important to me what he says or what he thinks."
Almunia, who recently signed a new deal, also insisted any new keeper signing would be welcomed at Emirates stadium.
"If another goalkeeper comes in he will be made welcome," he says. "I hope we can have a good atmosphere with all the goalkeepers working together. I signed my contract because my heart is with Arsenal."
