Lloris is the 22-year-old keeper who starred in the Champions League midweek frustration of Liverpool.
"A fantastic keeper who will be a fantastic keeper in the future," said Wenger.
When asked if he though Lloris was France's best keeper for some time, Wenger gave an emphatic "Yes".
And when asked if he could one day be an Arsenal keeper, Wenger paused, before saying: "I don't know. At the moment we don't need a keeper."
