Shearer thinks they will have enough to lift themselves out of danger.
He told The Journal: "The additions made in January have made all the difference and these days I expect them to win most game they play.
"They have impressed, while I'm a huge fan of Cabaye. I think he is an excellent player.
"If they can steer clear of any more injuries, then they definitely have a chance.
"I have no worries about Newcastle being relegated. I did before they signed those players in January."
