"I haven't discussed Paul's future with him but on the evidence we have seen at the moment there is no reason why he shouldn't [stay another year],"
Scholes made his comeback as a second-half substitute in Manchester United's FA Cup victory over Manchester City in January, and the one-club-man has made the starting lineup on numerous occasions since.
Ferguson has now claimed that Scholes was wrong to call time on his career at the end of last season, as well as revealing that he knew the veteran midfielder was still good enough for Premier League football after seeing him train with the reserves.
"When I said to him last year you'll give me 25 to 30 games it wasn't enough for him. But I think he may look at it differently now.
"He knew right away when he went coaching with the reserves and took part in the sessions he could hack it."
Since his return, Scholes has made 10 appearances and scored twice, igniting speculation over how long he can continue for in his second spell.
Sunday's away fixture against Tottenham would see Scholes move to within one game of joining club legend Bill Foulkes at third place in Manchester United's all-time appearance records, and his manager sees his recent performances as proof that he can carry on.
"He came to me and said he'd made a mistake. The evidence we are seeing now is he is right. His form has been fantastic."
Ferguson also took the opportunity to praise his other long-standing servant, Ryan Giggs, after he marked his 900th appearance for the club against Norwich last weekend with a match-winning goal.
"To get to 900 games is beyond anyone now," he said. "In the modern day, nobody will do that for one club."
