The 37-year-old is reported to want to continue playing but Sarri said he would welcome Terry back at Stamford Bridge if he made a decision to pursue a coaching career.
" Here is John Terry's home, he would be very important for everyone here".
The defender is thought to be being tracked by several clubs from across the globe with Terry said to have most recently declined a move to Russian club Spartak Moscow. I'm not in search of records like some other players. "Chelsea is his home, of course". He told me he wants to play. If I can score between 15 and 20 goals each season, I will be very happy. He has won everything with the club, so it's up to him. "Every day I think we need to improve - and we can".
There is no consideration for Terry returning to Stamford Bridge as a player, with Sarri prioritising young talent like Wales worldwide Ethan Ampadu.
The Belgian winger was Chelsea's saviour today, scoring a hat-trick to ensure Chelsea's fifth victory from five matches as they came from a goal down to beat Cardiff 4-1.
"At the moment I can answer City or Liverpool".
"I think at the moment Liverpool and Manchester City are another step up, so we have to improve, and I hope next season we can be on the same level". Cardiff has two points from five games.
"I think in this moment we are very unsafe in the offensive phase but we are not so solid as I want in the defensive phase".
Chelsea have enjoyed a stellar start to the new Premier League season, and they'll look to keep their momentum going on Saturday.
"For me, it's a pleasure", Sarri said when asked if his days are long.
"Yesterday [Thursday] there were problems with fever for Emerson [Palmieri] and [Davide] Zappacosta, and a little problem after the match with the national team for Loftus-Cheek".
Sarri is known as a heavy smoker and said during the worldwide break his father was trying to persuade him to quit. He joined an elite club of Carlo Ancelotti (Chelsea), Pep Guardiola (Manchester City) and Craig Shakespeare (Leicester).
Speaking to Chelsea's official app, The 5th Stand, Terry said: "Still undecided what I'm doing next. We all have to help him to score goals and help him to continue like this".
Sarri established a reputation in Italy as a pure coach who is obsessed with thinking about football and preparing meticulously for his opponents, but the vibe he gives off is not as intense as the one that surrounded Antonio Conte during his two years at Cobham. "No more". He added: "Then I'd like to start again".
