"It was a bolt out of the blue - as far as I was concerned I was coming back to Charlton in pre-season to hopefully get promoted next year," McCarthy told the South London Press.
"But I got a call from my agent a couple of weeks ago saying there was an offer being put forward from Crystal Palace.
"Generally if a club accepts a bid it tells its own story and when I spoke to Neil Warnock he just came across as a man I think I'll have a great relationship with. He will maybe appreciate me as a player a little bit more.
"He's said he knows full well what he's getting from me and what I'll bring to Crystal Palace. That's filled me full of confidence."
