Giggs extended his record of scoring in every Premier League campaign with his goal in Wednesday's 5-0 win at Fulham. He subsequently revealed he was due to speak with Ferguson about his future plans.
Now 38, Giggs has been on a rolling one-year contract since he hit the 30 mark.
Though long-time team-mates Paul Scholes and Gary Neville have both retired in the past 12 months, Giggs seems to go on and on. Providing the veteran Welshman wants to, Ferguson cannot see any reason why he should not stay for yet another campaign.
"I think Ryan can play another year," the Scot said. "There is no evidence at this moment in time that his energy, stamina or speed are decreasing. In fact, it's exactly the same as it was the last two or three years. It's amazing.
"I know it's mid-season now and it all depends on what Ryan thinks about his future, too. He knows he can't go on forever, we know he can't go on forever, but he can play for another year."
