The BBC pundit has been discussing the Magpies' relegation battle.
Indeed, Sinclair says Newcastle possess too much quality to still be in the relegation zone by the end of the season, despite the fact they remain there at the end of January.
Meanwhile, the pundit also feels Steve McClaren's experience is another advantage for the St James' Park outfit, despite his poor performance in the job so far.
Sinclair is quoted as telling 90min.com by the Chronicle: "I do feel they’ll have too much to go down and on top of that they’ve got the experienced manager there.
"I think with Steve McClaren you’ve got an experienced manager. He won things, he’s managed top, top teams and at international level, he’s been involved with that as well. So I think they’ve got an advantage on that side of things with the manager they’ve got in place."
Newcastle currently sit two points off safety, even though McClaren continually claims the Magpies won't have any problems surviving if they keep playing as well as they are.
Sunderland are a further two points back, while Aston Villa are way off the pace.
Norwich City are next in line but then there's Bournemouth and Swansea City. Those are the three biggest candidates to go down in place of Newcastle, as West Brom and those above them realistically look too far ahead of the Magpies.
