Maurizio Sarri has admitted that he doubts Chelsea would keep him as head coach if he went four years without winning a trophy at Stamford Bridge.
Sarri's Tottenham counterpart Mauricio Pochettino has managed precisely that feat, with the two coming up against each other for the first time in the Premier League on Saturday.
They both share the unwanted distinction of not having won any silverware in their managerial careers, but Sarri admits that his drought probably needs to end if he is to remain in his post.
Asked if he would be afforded four years at Chelsea without a trophy, Sarri told Sky Sports: "I don't think so, but I don't know.
"It's up to the club - if it's more important to win, or more important to improve the players.
"I want to win something, just to avoid this question. Sometimes there are the conditions for winning. Sometimes not.
"It's clear he (Pochettino) is a very important coach, with a trophy or without a trophy."
