The veteran midfielder is out of contract in Turin at the end of the season, and reports suggest a move to the Premier League could be on the cards.
"I don't know if [I] will be at Juventus or another team [next season]," Pirlo said after Italy's 1-1 draw with Germany on Friday.
"My future? There is the rest of the season to talk about it. We'll see.
"I am optimistic. I want to keep playing because I'm good and enjoy it."
While Pirlo himself insists he is in no rush to put pen to paper with Juventus, according to Gazetta dello Sport his club are as interest from Tottenham increases.
The Italian are said to be preparing a two year deal worth €8 million to keep him from the clutches of Spurs - and they are optimistic he'll take them up on that offer.
The north London club are believed to be ready to offer Pirlo a three-year deal at White Hart Lane that would take him up to the age of 37.
Tottenham spent well over £100 million on new players over the summer in order to secure their place amongst the Premier League elite.
While they are only three points adrift of 2nd placed Liverpool they have struggled to find the back of the net regularly so far, and have mustered just nine goals in 11 games.
