The Blues missed out on Champions League qualification with a miserable display at St James' Park – though three points would have proved insufficient to earn a top-four spot with Liverpool winning at home against Brighton and Hove Albion.
Asked if the outing at Wembley would be his last with the club, Conte replied: "No, I don't think so. In this season, for sure.
"I am committed to this club, this is important for me. Not speculation around me. It is important what the club thinks, not you.
"I have a contract and the club know very well the situation. After Saturday we go on vacation and then we will see next season."
The Italian was critical of his team's "approach and desire" against Newcastle and refused to discuss the ramifications of missing out on a spot in the Champions League.
"I think I am the last person to speak about this," said Conte. "You can ask the club about the damage.
"I am working with my players this season and it is not right to say something about this. Other people can judge our season.
"For sure we must change, if we play a game like this in the FA Cup we don't have a chance. We have six days to change our approach and desire and will to fight.
"For this I am the first person to answer as I am the coach of this team and I am the first person to answer for this game."
"I like to play to win. This is my first season that I didn't win the title. Three with Juventus and one with Chelsea and when I start I have always won," he said.
"There is a great disappointment for me as I like to play to win."
