United have been linked with many creative midfielders, including Modric, Wesley Sneijder and Samit Nasri, to fill the void left by 36-year-old Scholes.
Scholes says he is impressed with the names who could potentially replace him at Old Trafford but revealed that Modric in particular stands out.
"The ones who have been linked all look like they are capable of playing for United," he told Manchester Evening News.
"The three linked the most with United are all great top players. Of the three, Modric, when we've played against him, has been the one I have been most impressed with.
"Whenever we played Tottenham, he was the one who stood out."
Scholes also said he felt the talk of replacing him was a little unnecessary.
“I think people are obsessed with having to replace me," he added. "If you look at the facts over the last couple of years. I haven’t played in the big games. So I don’t think there is that much that needs replacing."
