The former Dons boss has been previewing Sunday's top-of-the-table clash.
Sir Alex Ferguson feels Aberdeen won't go to Celtic Park with any fear but has also outlined where the Scottish champions can beat his former side on Sunday,the Scottish Daily Mail report following an interview with Sky Sports.
Ferguson is relishing the top-of-the-table clash this weekend, which sees second-placed Aberdeen travel to leaders Celtic, and has praised the job Dons boss Derek McInnes has done.
The position McInnes has got Aberdeen into means his side will head into the Celtic clash with no fear, according to Ferguson, but he has also acknowledged the advantages the Bhoys have in their favour.
The ex-Aberdeen boss believes Celtic have good goalscorers, as well as a 'fantastic history.' He does, however, feel it will be a close affair.
"It will be close. Celtic have the more experience and a fantastic history and they have some good goalscorers in their team," Fergie told Sky Sports.
"It will be difficult for Aberdeen but Derek McInnes has done a fantastic job up there he really has. It’s been a few years since they have been in a position like they are in now.
"All credit to the manager, he has done a really good job. I don’t think they will be afraid going to Celtic Park."
Since losing their Scottish League Cup semi-final to Dundee United, Aberdeen have won three out of three Premiership games - all by a margin of at least three goals.
Celtic, though, are on quite a domestic run themselves and were only knocked out of the Europa League on Thursday night by one goal against Inter Milan, having had Virgil van Dijk sent off before half-time.
Whoever prevails, Fergie will no doubt be watching.
