Former Chelsea striker Hernan Crespo is happy seeing Enzo Fernandez at Stamford Bridge.
Crespo worked with Fernandez as coach of Defensa y Justicia.
He told the Daily Mail: "He made me happy in December so, so much with [winning] the World Cup.
"Now it is a second happiness he has given me in a short time because he joined Chelsea. I'm very happy, very proud for him because he is a very, very good guy.
"He [Fernandez] is [Claude] Makalele plus [Frank] Lampard. If you need him in the Makelele position he can play very well.
"This guy can also smell the goal, good shot from outside the box so if you need him behind the striker, Lampard or [Michael] Essien, he can do it.
"As a manager, having a player that can play in lots of positions, it's really important in football today. He can do everything as a midfielder. He can be one of the best midfielders in history."
