The Sunderland boss once failed at Newcastle - but he would've been perfect for the St James' Park outfit this season.
A look at Newcastle United's form could explain why they lost 5-1 to Crystal Palace.
But a look at the result Sunderland picked up just a few days earlier at the same ground makes a mockery of the Magpies.
Indeed, Sam Allardyce guided his side to a 1-0 win, keeping a clean sheet where Newcastle conceded five.
So what was Steve McClaren's excuse? Isolating Yannick Bolasie and Wilfried Zaha earned the Black Cats all three points but McClaren went to Selhurst Park as a clueless, tactically inept manager who may as well call himself John Carver.
Look what McClaren is doing with Newcastle. And look what Allardyce has done at Sunderland already.
It begs the question... is Big Sam the only man that could have actually pulled this Newcastle squad round?
The 61-year-old failed at Newcastle once - but only when the club were aiming higher than when it simply comes to staying up. In that situation, Allardyce is completely the wrong man for the job.
But, when it comes to getting back to basics, sorting a squad out and keeping them safe, Big Sam is your man. When he came in at Sunderland, the Black Cats were in an abysmal state. Allardyce, however, has transformed that rather quickly.
McClaren, meanwhile, tries to emphasises aimless possession and smiles every time Newcastle lose, promising - almost with glee - yet more adversity.
