Veteran German goalkeeper Jens Lehmann has launched a scathing attack against his club manager Arsene Wenger and the two goalies keeping him on the sidelines at Arsenal.Lehmann made a host of calamitous errors at the beginning of the season and was quickly replaced by Wenger with Spaniard Manuel Almunia. He found himself barred even from the bench for this week’s Premier League match against Bolton, with young Pole Lukasz Fabianski preferred as back-up to Almunia.And now the German stopper has questioned his manager’s thinking and even the credentials of his teammates, while claiming he is being humiliated.Speaking in an interview with German pay-TV station Premiere, Lehmann declared: “It could be that at some point I feel like commenting on the whole issue, but right at the moment I just accept everything as part of the humiliation. You have to let it happen.“But I think — and this is directed towards my dear coach — that you should not humiliate players for too long. I am an Arsenal player and I will not just fade away quietly.” Having criticised his boss, he turned his attentions to Almunia and Fabianski. “I am convinced I will soon be playing again,” he said. “Almunia hasn’t shown that he can win us matches just yet. I have been through this situation once and know how the other keeper is situated mentally. I can’t imagine he will handle this.“Wenger has spoken of three world-class goalies. I guess I must be one of them. The others have proven their class by winning titles? I’m just thinking about it, and I can’t recall any. But yet today they are considered world class.”
