The 30-year-old Dutchman was not match fit when he arrived at the Liberty Stadium but midfielder Britton has been impressed by his performances in recent weeks.
Britton said: "Cedric is a very good player. When he first arrived, he wasn't match fit as he's not been training but he's getting there now.
"What a player to get on a free, he's good on the ball and obviously got his goal at the weekend, But he has a lot more to his game than that.
"He works very hard and he is a great player to have in the team."
