That doesn't compare to his spell at Newcastle United where Ambrose found it difficult to progress while the north-east club went between different managers.
He said: "When Graeme Souness came in I felt I wasn't really part of his plans so my move to Charlton was perfect for me to try and get more first team football. It's been a big season in my career because I've learned I can last a whole season now."
It could of course end with an FA Cup final appearance, after last week's semi-final draw ensured neither Charlton or Middlesbrough would face Liverpool or Chelsea in the next round.
Addicks boss Alan Curbishley said: "We're just pleased to have avoided the big two."
