"I've still not ruled out [the league game against Sunderland on] Sunday being my last game and retiring from football", he said.
However, it seems followers from all clubs were aware this was something special for a legend of the game - who now has five Premier League titles to his name.
English premier league Champions Chelsea have defeated Watford 4-3 in the English Premier League.
Terry, making his 716th Chelsea appearance, put his side ahead in the 22nd minute at Stamford Bridge, but it was from the 36-year-old's loose header that Etienne Capoue equalised two minutes later.
Chelsea, as so often this season, found a way to win as substitute Cesc Fabregas struck from the edge of the area with three minutes left.
Terry somewhat surprisingly suggested after the game against Watford that he could hang up his boots altogether at the end of the season, but Conte does not think the centre-back will retire just yet.
The Hornets had Sebastian Prodl sent off for a second yellow card in stoppage time.
Conte told Chelsea TV: "We could become the first team to reach this target".
Manager Antonio Conte applauded all sides of the ground as chants of "Antonio, Antonio" bellowed around Stamford Bridge in the opening minute.
"Tottenham last season fought to win the title and Chelsea finished 10th". For this reason, for me and our fans, every single player must be a king and I must be pleased to have this kind of player'. "So far we have worked nine months together, but now the players know my idea and trust in my work, I think we can get better".
"At the moment I have 13 or 14 players who deserve to play the FA Cup final who are in very good form". Only Tottenham (31 wins in 1960-61) and Liverpool (30 wins in 1978-79) have broken won at least 30 games in a season.
