Swansea City captain Ashley Williams is pleased over his maturing partnership with Federico Fernandez.
The pair are communicating in Spanglish, admits the Wales defender.
Williams said: "He speaks English... he just doesn't speak to you lot!
"I'm enjoying playing with him, he's a very good defender.
"He is still learning the system, especially on the ball, and I think you can see that sometimes.
"But that's a given really because it's different in this team at centre-half on the ball, but I think he's doing really well and I'm happy playing with him."
