No chance of that at all... Kovacic hasn't improved at all since joining Madrid. What you are fawning over is a player who looked good at Inter years ago, you are essentially reminiscing about what he was like.
Jorginho is the brain of the football team, its not too much of a stretch to liken him to Xavi. He is the pace setter and the guy who gets teams to play, he is without doubt the player Chelsea have been dying for ever since 2011 when we wanted Modric.
Cesc was never a regista we just played him as one, Jorginho is the real article.
