The pair worked together during their time in Italy with Inter Milan, where Hodgson was manager between 1995 and 1997.
With pressure already mounting on the former England boss after his short time so far at Selhurst Park, Carlos has piled on more with criticism of the 70-year-old's knowledge of the game.
“Hodgson’s stay at Inter destroyed me,” Carlos told Planet Football. “He played me in midfield and I had to consider that there was a chance that this would ruin my career in the national side.
“It’s not that I did not have a good relationship with Hodgson. It is just that Hodgson doesn’t know much about football.
“When Inter lost in the UEFA Cup final against Schalke in 1996, it was purely because of Hodgson.”
Hodgson will be looking for his first points as Palace manager on Saturday, when his side host reigning Premier League champions Chelsea.
