"I have 40,000 thank-yous to say, so it will take me a while," Dudek told official publication LFC Magazine.
"It would be nice to play in the last game against Charlton. I would get to walk around the pitch and take it all in. I could hear the fans singing again. I don't know if it will be possible, it's up to the manager when he picks the team.
"I just want to say goodbye. If it is not possible then I will be the last person left on the pitch after the Charlton game."
