Giggs, who was appointed as a player-coach at Old Trafford at the start of the season, has claimed that he has no intention of hanging up his boots just yet.
Speaking at a press conference, Wenger gave credit to the Welshman and likened him to former Arsenal star Dennis Bergkamp.
"He reminds me a bit of Bergkamp," Wenger told reporters. "To deliver these performances at 40 is something special."
Giggs started for United in Wednesday's 5-0 win over Bayer Leverkusen in the Champions League.
