Napoli president Aurelio De Laurentiis admits Maurizio Sarri's resignation at Lazio surprised him.
The former Napoli coach has offered his resignation in the last 24 hours.
Before their Champions League defeat at Barcelona, ADL said: “That really shocked me. After the first experiences where you qualify as a professional, you must take on your share of the responsibility.
"If you accept a role, you must carry it on to the end, out of respect for the club, the players and the fans.
“It's too easy to hand in your resignation, that is what a loser does. I do not know the motivation behind it, but (Lazio President Claudio) Lotito does not seem aggressive. He is a man with qualities and there should've been a solution found for a team that can't just be dumped near the end of the season."
