Scholes is a lifelong Oldham fan and has often been linked with taking charge at Boundary Park.
And the 44-year-old finally landed his dream job, replacing Frankie Bunn who was sacked in December.
Scholes has spent recent seasons as a TV pundit and became renowned for his scathing criticisms of Jose Mourinho.
Gary Neville also ventured into management in 2015 but his disastrous spell in charge of Valencia ended in tears after just four months.
“About to be sacked after few games like Gary Neville.”

And football fans have backed Scholes to fail at Oldham and suffer the same fate as his former team-mate.
“About to be sacked after few games like Gary Neville and (Thierry) Henry,” said one fan on Twitter.
While another added: “Lets see if he can back up, the absolute garbage he talks as a pundit.
“I foresee another Neville saga replicated.”
“Going to end up worse than Henry and Neville,” tweeted a third.
And one supporter insists he deserves to be unsuccessful following his time on TV.
“Hope he does a @GNev2 and fails miserably for all of his ridiculous comments as a pundit,” they tweeted.
Oldham are currently 14th in League Two, nine points off the play-offs.
And Latics owner Abdallah Lemsagam has backed Scholes to bring success back to the club.
“Paul has won everything there is to win in football,” he said.
“He is a man who will bring a lot of footballing knowledge and his hunger to succeed in management will be there for everyone to see.
“It’s no secret how much he has wanted this job in the past and how much he loves this club, so I’m very happy to bring him into our family at Oldham Athletic.
“Paul will have my backing 100 per cent and hopefully we can work together to bring success back to this club.”
