Napoli defender Elseid Hysaj could have joined former coach Maurizio Sarri at Chelsea last summer, but Partenopei president Aurelio De Laurentiis prevented the move, according to the player's agent.
Mario Giuffredi, who represents Hysaj, has supported his client after recent criticism of his form, and said the right-back could have left for Stamford Bridge and the Premier League.
Speaking to Radio Kiss Kiss Napoli (h/t Goal), Giuffredi said:
"Those who criticise him probably never make mistakes, but the rest of us are mere mortals.
Without that clause he probably would have gone to Chelsea this summer.
