Pochettino doesn't seem confused anymore and he will definitely have put together the right formation against Newcastle and will definitely try to steal full points.
IMO, the match against Newcastle will be the key for Chelsea ... will they truly make a comeback and be ready to shake up the top 4, or is it all just bullshit?
If Chelsea wins, at least by a margin of two goals against Newcastle, it strongly suggests that Chelsea is poised to return to the top 4 and compete with Man City, Liverpool, and Spurs. However, if they lose, it's worth reconsidering because that would confirm Chelsea as a truly unstable team.
