"Martin was a character, for us he was a father-figure, whereas Ramos, it is just tactics and nothing else," he said.
"In training, we do a lot of 11 v 0 and stuff on the blackboard to work on our progress with the ball."
Kaboul also claimed that Ramos does not communicate with the players and that the Spanish coach has not given him a chance since replacing Jol.
"I played the entire first half of the season but since the change of manager, I have not played," said Kaboul.
"I have had no explanation from him. He doesn't talk with anyone. Communication doesn't exist with him. He isn't playing me? That is his choice - I respect it, I am a professional.
"I am young and it is the first time this has happened to me in my career. But I am not surprised because when you are a footballer, you must be prepared for that, for good and bad times.
"Ramos has not really given me a chance. When a player doesn't have the confidence of his coach, he can't do much on the pitch. But when a coach has confidence in you, you take the handbrake off and you race away."
