Napoli manager Maurizio Sarri says he has been left "embittered" by the way Gonzalo Higuain's transfer to Serie A champions Juventus panned out.

Last season's Italian league top scorer swapped clubs in a £90 million deal which strengthens Juve but severely weakens Napoli.

And as Sarri told Corriere dello Sport, it has left a sour taste.

"It's hard for me to speak of Higuain after seeing him wearing the Juventus shirt. I'll talk about it, but not gladly. It was his own decision, because our offer matched what was offered away from here," he said.

"From a personal point of view, I'm left embittered. I was expecting at least a phone call, be it just five minutes before he had his medicals. But I'm old enough not to be surprised. The lads too expected a farewell. That I know of, there was nothing."

The move also drew criticism from Roma legend Francesco Totti earlier in the week, when he described the transfer as a "disaster".
