The man expected to be appointed new Newcastle United boss has one big task, according to the ex-Nottingham Forest manager.
Indeed, the former Nottingham Forest boss was full of praise for the ex-Middlesbrough and England coach but feels he has one big task at St James' Park: getting the fans on his side.
And Pearce feels Kevin Keegan was the biggest example of doing so, with the former Newcastle manager getting the fans on side 'fantastically.'
With the separation between club and supporters at present, embodied by the mass boycott of the Magpies' clash with Tottenham Hotspur last season, the former Forest man feels McClaren has to unite the club a lá Keegan.
Pearce told Sky Sports News: "The first thing he has to do is get the fans on his side. Kevin Keegan did that fantastically. The fans and the football club were one when Keegan was there.
"That football club and that city was united. Kevin had that club going forward with momentum and everyone had a smile on their face.
"The first thing Steve has to do is put a smile back on the supporters' faces and make them feel inclusive at that football club."
McClaren's career, of course, has been quite a rollercoaster to date. At Middlesbrough, McClaren reached the UEFA Cup final but was thrashed in that very final.
He later became England boss, only to see that job end in tears. The 54-year-old then won the Eredivisie with FC Twente but also enjoyed an unsuccessful second spell with the Dutch club (as well as an underwhelming time at Wolfsburg and Nottingham Forest).
McClaren's most recent job saw plenty of highs but finished on a resounding low at Derby County. So the man expected to be unveiled Newcastle boss never does things without both the good and the bad...
