Napoli President, Aurelio De Laurentiis was the main reason Chelsea could not sign Elseid Hysaj during the summer transfer window, according to the player’s agent Mario Giuffredi.

Chelsea manager, Maurizio Sarri was expected to come along with Hysaj to London after years of working together at two different clubs but the transfer never materialised.

And Hysaj’s agent claims it is because De Laurentiis would not allow the move to go through.

The defender wanted to join the Blues, but Giuffredi explained it was impossible after Napoli agreed to allow Jorginho move to the Stamford Bridge.

“Those who criticise him probably never make mistakes, but the rest of us are mere mortals,” Giuffredi told Radio Kiss Kiss Napoli.

“Without that clause he probably would have gone to Chelsea this summer.

“People forget that he was one of the best two or three full-backs in Europe last season. Then it just takes two or three matches for him to become a donkey.

“I always say to let everyone talk and then respond on the pitch.”
