The 36-year old French striker, who captains the club, is in the final year of his Red Bulls contract and has yet to decide whether he will play on in 2015.
Petke spoke to reporters on Monday regarding any forthcoming decision from the former Arsenal and Barcelona man, suggesting that the 2014 MLS season was the main emphasis for the ageing-yet-supremely-classy forward.
However, Petke did indicate that talks of some description will take place later in the campaign when the Red Bulls have a better grasp of their standing in the competition.
"Obviously, Thierry wants to focus on the now and focus on this season, getting off to a good start," said Petke.
"He's continuing to do well in preseason and I think that's (his future) the farthest thing on his mind, to be honest with you. I think we'd all be foolish not to realize that at some point, midseason on, there will most certainly be discussions. There has to be.
"But at this stage right now, Thierry is doing a great job at prioritizing that it's all about the now and he understands that there's going to be questions and opinions. But until that point comes that both sides, Thierry and his representatives and us, feel that we need to address it, we're focusing on this preseason right now and the beginning of the season."
