Wenger's current deal expires in June.
"We are in no hurry," said Wenger.
"We are in September and my contract finishes in June, there is a long way to go.
"There is no need to plan (any talks). I have said many times I want to do well with this club and in the end I will sit down and think 'how well have I done with the team I have had?' That has to be sufficient for me to decide yes or no.
"One of the main judgments you can have about a manager is how well he does with his team."
