Arsenal keeper Jens Lehmann has warned he may publicly air his grievances with Arsene Wenger if he does not play soon.
Lehmann is not happy at playing second fiddle to Almunia
Lehmann's errors and injuries at the start of the season gave Manuel Almunia his chance and he is now first-choice ahead of the fit-again German stopper.
The 37-year-old told German TV channel Premiere: "I think - and this is aimed at my dear manager - one shouldn't humiliate players for too long.
"It's possible that some day I'll feel like talking about the whole issue."
Lehmann's comments came after he was left out of the Arsenal squad against Bolton last Saturday - a game he expected to play in after impressing for Germany earlier this month.
Almunia has not yet showed that he can win matches for us
But Wenger, who dropped Lehmann after he gifted Blackburn an equaliser in the 1-1 draw on 19 August, stuck with Almunia and put young keeper Lukasz Fabianski on the bench.
Almunia was once again in goal for Wednesday's 7-0 win over Slavia Prague, although Lehmann did return to the bench.
"At the moment I'm just swallowing it all as part of the humiliation. That's something one has to take in, " Lehmann said.
"But I'm an Arsenal player and I won't just fade away quietly."
Wenger was asked about Lehmann's outburst following his side's demolition of Slavia.
"I don't want to humiliate anybody," said the Gunners boss. "We have three world-class goalkeepers and we can only play one."
But Lehmann is bemused by Wenger's assertion that he has three "world-class" goalkeepers to pick from.
"One of them must be me," he suggested. "The other two have proved their class by winning titles? If I think about that, I can't recall any. I guess today you're nevertheless world-class."
Lehmann won the Uefa Cup in 1997 with Schalke 04, the Bundesliga title in 2002 with Borussia Dortmund and the Premier League with Arsenal in 2004.
And he made it clear he feels he should still be the number one at the Emirates Stadium.
"I'm convinced that I'll be playing again. Almunia has not yet showed that he can win matches for us," Lehmann added.
"I've experienced this situation before and know what the others are expecting from the goalkeeper. I can't imagine he'll be able to handle that."
