«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.»
Salford City said Scholes would resign as a club director, but will retain his shareholding alongside former United teammates Gary and Phil Neville, Ryan Giggs, Nicky Butt, David Beckham and businessman Peter Lim.
«Although Paul was never operational in Salford City he will resign as a director of the football club, allowing him to focus completely on his new role at Oldham,» the National League club said in a statement.
«From the start we have always said that each of the ‘Class of 92’ would offer different levels of commitment dependant on their individual roles.»
Scholes has limited coaching experience, including four matches alongside Ryan Giggs when his former teammate took caretaker charge of United following David Moyes’s sacking in 2014.
The former England international has worked as a television pundit for BT Sport in recent years.
Oldham sacked Frankie Bunn in December and academy coach Pete Wild was put in temporary charge of the team.
